    High-level information processing in the mammalian cortex requires both segregated processing in specialized circuits and integration across multiple circuits. One possible way to implement these seemingly opposing demands is by flexibly switching between states with different levels of synchrony. However, the mechanisms behind the control of complex synchronization patterns in neuronal networks remain elusive. Here, we use precision neuroengineering to manipulate and stimulate networks of cortical neurons in vitro, in combination with an in silico model of spiking neurons and a mesoscopic model of stochastically coupled modules to show that (i) a modular architecture enhances the sensitivity of the network to noise delivered as external asynchronous stimulation and that (ii) the persistent depletion of synaptic resources in stimulated neurons is the underlying mechanism for this effect. Together, our results demonstrate that the inherent dynamical state in structured networks of excitable units is determined by both its modular architecture and the properties of the external inputs.

    Reservoir computing is a machine learning paradigm that transforms the transient dynamics of high-dimensional nonlinear systems for processing time-series data. Although the paradigm was initially proposed to model information processing in the mammalian cortex, it remains unclear how the nonrandom network architecture, such as the modular architecture, in the cortex integrates with the biophysics of living neurons to characterize the function of biological neuronal networks (BNNs). Here, we used optogenetics and calcium imaging to record the multicellular responses of cultured BNNs and employed the reservoir computing framework to decode their computational capabilities. Micropatterned substrates were used to embed the modular architecture in the BNNs. We first show that the dynamics of modular BNNs in response to static inputs can be classified with a linear decoder and that the modularity of the BNNs positively correlates with the classification accuracy. We then used a timer task to verify that BNNs possess a short-term memory of several 100 ms and finally show that this property can be exploited for spoken digit classification. Interestingly, BNN-based reservoirs allow categorical learning, wherein a network trained on one dataset can be used to classify separate datasets of the same category. Such classification was not possible when the inputs were directly decoded by a linear decoder, suggesting that BNNs act as a generalization filter to improve reservoir computing performance. Our findings pave the way toward a mechanistic understanding of information representation within BNNs and build future expectations toward the realization of physical reservoir computing systems based on BNNs.

    Neuronal networks in dissociated culture combined with cell engineering technology offer a pivotal platform to constructively explore the relationship between structure and function in living neuronal networks. Here, we fabricated defined neuronal networks possessing a modular architecture on high-density microelectrode arrays (HD-MEAs), a state-of-the-art electrophysiological tool for recording neural activity with high spatial and temporal resolutions. We first established a surface coating protocol using a cell-permissive hydrogel to stably attach a polydimethylsiloxane microfluidic film on the HD-MEA. We then recorded the spontaneous neural activity of the engineered neuronal network, which revealed an important portrait of the engineered neuronal network–modular architecture enhances functional complexity by reducing the excessive neural correlation between spatially segregated modules. The results of this study highlight the impact of HD-MEA recordings combined with cell engineering technologies as a novel tool in neuroscience to constructively assess the structure-function relationships in neuronal networks.

    Abstract An increasing demand for bioelectronics that interface with living systems has driven the development of materials to resolve mismatches between electronic devices and biological tissues. So far, a variety of different polymers have been used as substrates for bioelectronics. Especially, biopolymers have been investigated as next-generation materials for bioelectronics because they possess interesting characteristics such as high biocompatibility, biodegradability, and sustainability. However, their range of applications has been restricted due to the limited compatibility of classical fabrication methods with such biopolymers. Here, we introduce a fabrication process for thin and large-area films of chitosan nanofibers (CSNFs) integrated with conductive materials. To this end, we pattern carbon nanotubes (CNTs), silver nanowires, and poly (3,4-ethylenedioxythiophene):poly (styrenesulfonate) (PEDOT:PSS) by a facile filtration process that uses polyimide masks fabricated via laser ablation. This method yields feedlines of conductive material on nanofiber paper and demonstrates compatibility with conjugated and high-aspect-ratio materials. Furthermore, we fabricate a CNT neural interface electrode by taking advantage of this fabrication process and demonstrate peripheral nerve stimulation to the rapid extensor nerve of a live locust. The presented method might pave the way for future bioelectronic devices based on biopolymer nanofibers.

    Reservoir computing provides a novel framework to understand how the dynamics within biological neuronal networks (BNNs) is linked to information processing. Here, we used micropatterned substrates to fabricate BNNs with modular topology, one of the important structural features of brain networks, and realized a reservoir system with the modular BNN. Using image and time-series classification tasks, we evaluated the reservoir computing properties of the BNN reservoirs. The results show that modularity facilitates the separation between the trajectories of the neuronal responses to different spatial patterns, pointing to the functional advantage of the animals to modular topology within the nervous systems.

    The bilayer lipid membrane (BLM) is the main structural component of cell membranes, in which various membrane proteins are embedded. Artificially formed BLMs have been used as a platform in studies of the functions of membrane proteins, including various ion channels. In this review, we summarize recent advances that have been made on artificial BLM systems for the analysis of ion channel functions. We focus on two BLM-based systems, cell-membrane mimicry and four-terminal BLM systems. As a cell-membrane-mimicking system, an efficient screening platform for the evaluation of drug side effects that act on a cell-free synthesized channel has been developed, and its prospects for use in personalized medicine will be discussed. In the four-terminal BLMs, we introduce “lateral voltage” to BLM systems as a novel input to regulate channel activities, in addition to the traditional transmembrane voltages. Such state-of-the-art technologies and new system setups are predicted to pave the way for a variety of applications, in both fundamental physiology and in drug discovery.

    We investigated the bactericidal activity of bulk nanobubbles (NBs) using E. coli, a model bacterium. Bulk NBs were produced by forcing gas through a porous alumina membrane with an ordered arrangement of nanoscale straight holes in contact with water. NBs with different gas contents, including CO2, O2, and N2, were generated and evaluated for their bactericidal effects. The survival rate of E. coli was significantly reduced in a suspension of CO2-containing NB (CO2-NB water). The N2-NB water demonstrated a small amount of bactericidal behavior, but its impact was not as significant as that of CO2-NB water. When E. coli was retained in O2-NB water, the survival rate was even higher than that in pure water (PW). We investigated the generation of reactive oxygen species (ROS) in NB suspensions by electron spin resonance spectroscopy. The main ROS generated in the NB water were hydroxyl radicals and OH·, and the production of ROS was the strongest in CO2-NB water, which was consistent with the results of the bactericidal effect measurements. We assumed that NB mediated by ROS would exhibit bactericidal behavior and proposed a kinetic model to explain the retention time variation of the survival rate. The results calculated based on the proposed model matched closely with the experimental results.

    The reconstitution of ion-channel proteins in artificially formed bilayer lipid membranes (BLMs) forms a well-defined system for the functional analysis of ion channels and screening of the effects of drugs that act on these proteins. To improve the efficiency of the BLM reconstitution system, we report on a microarray of stable solvent-free BLMs formed in microfabricated silicon (Si) chips, where micro-apertures with well-defined nano- and micro-tapered edges were fabricated. Sixteen micro-wells were manufactured in a chamber made of Teflon®, and the Si chips were individually embedded in the respective wells as a recording site. Typically, 11 to 16 BLMs were simultaneously formed with an average BLM number of 13.1, which corresponded to a formation probability of 82%. Parallel recordings of ion-channel activities from multiple BLMs were successfully demonstrated using the human ether-a-go-go-related gene (hERG) potassium channel, of which the relation to arrhythmic side effects following drug treatment is well recognized.

    <title>Abstract</title> Eukaryotic in vitro translation systems require large numbers of protein and RNA components and thereby rely on the use of cell extracts. Here we established a new in vitro translation system based on rice callus extract (RCE). We confirmed that RCE maintains its initial activity even after five freeze-thaw cycles and that the optimum temperature for translation is around 20°C. We demonstrated that the RCE system allows the synthesis of hERG, a large membrane protein, in the presence of liposomes. We also showed that the introduction of a bicistronic mRNA based on 2A peptide to RCE allowed the production of two distinct proteins from a single mRNA. Our new method thus facilitates laboratory-scale production of cell extracts, making it a useful tool for the in vitro synthesis of proteins for biochemical studies.

    Artificial bilayer lipid membranes (BLMs), along with patch-clamped<br /> membranes, are frequently used for functional analyses of membrane proteins. In<br /> both methods, the electric properties of membranes are characterized by only<br /> one parameter, namely, transmembrane potential. Here the construction of a<br /> novel BLM system was reported, in which membrane voltages can be controlled in<br /> a lateral direction in addition to conventional transmembrane direction. A<br /> microaperture was fabricated in a Teflon film and Ti electrodes were evaporated<br /> around the aperture. BLMs were reproducibly formed in the aperture without<br /> being affected by the presence of the electrodes. The application of a lateral<br /> voltage induced no significant changes in the electric properties of the BLMs,<br /> such as baseline current, transmembrane resistance, and transmembrane<br /> capacitance. In contrast, lateral voltages clearly affected the activities of<br /> biological ion channels, suggesting that the lateral voltage might be a useful<br /> parameter for analyzing channel activities. The present Teflon-based system in<br /> which multidirectional voltages can be applied to BLMs represent a promising<br /> platform for the analysis of underlying functional properties of membrane<br /> proteins.

    We aim to develop a drug screening system based on a reconstitution system in which ion channels are embedded in an artificial lipid bilayer membrane (BLM). We have been developing stable BLMs based on silicon (Si) microfabrication. We previously reported on efficient incorporation of ion channels in BLMs. Here we applied this system to a cell-free synthesized hERG channel and tried to quantify drug side effects on this channel.

    Synaptic dysfunction and neuronal death are responsible for cognitive and behavioral deficits in Alzheimer's disease (AD). It is well known that such neurological abnormalities are preceded by long-term exposure of amyloid β-peptide (Aβ) and/or hyperphosphorylated tau prior. In addition to the neurological deficit, astrocytes as a major glial cell type in the brain, significantly participate in the neuropathogenic mechanisms underlying synaptic modulation. Although astrocytes play a significant key role in modulating synaptic transmission, little is known on whether astrocyte dysfunction caused by such long-term Aβ exposure affects synapse formation and function. Here, we show that synapse formation and synaptic transmission are attenuated in hippocampal-naïve neurons co-cultured with astrocytes that have previously experienced chronic Aβ1-40 exposure. In this abnormal astrocytic condition, hippocampal neurons exhibit decrements of evoked excitatory post-synaptic currents (EPSCs) and miniature EPSC frequency. Furthermore, size of readily releasable synaptic pools and number of excitatory synapses were also significantly decreased. Contrary to these negative effects, release probability at individual synapses was significantly increased in the same astrocytic condition. Taken together, our data indicate that lower synaptic transmission caused by astrocytes previously, and chronically, exposed to Aβ1-40 is attributable to a small number of synapses with higher release probability.

    N-methyl-D-aspartate (NMDA) stimulation is usually used to investigate a series of neuronal mechanisms involved in NMDA receptor-mediated Ca2+ signal. We here examined by using Ca2+ imaging technique whether the NMDA-induced Ca2+ signal is due to the exclusive activation of NMDA receptors or activation of voltage-dependent calcium channels (VDCCs) together with NMDA receptors in mouse hippocampal slices. In order to isolate each component of the Ca2+ signal, we used sodium channel antagonist tetrodotoxin (TTX), which prevents dendritic spikes and the following activation of VDCCs, and L-type VDCC antagonist nicardipine. The results showed that in the CA1 region, almost a half of the NMDA-induced Ca2+ signal was the TTX-sensitive component involved in indirect Ca2+ influx via VDCCs, while the other half was the TTX-insensitive component involved in direct Ca2+ influx via NMDA receptors. In addition, the TTX-sensitive component should be almost via L-type VDCCs. We further examined the effects of corticosterone (CORT), which is a principal glucocorticoid synthesized in the rodent adrenal cortex and secreted in response to stress, on each component. It has been reported that CORT acutely (nongenomically) suppress the NMDA-induced Ca2+ signal in the CA1 region. The present results, however, led us to a new finding that CORT enhanced the TTX-insensitive component and the suppressive effect of CORT reported so far should be attributed to the effect on the TTX-sensitive component.

    Reservoir computing is a machine learning paradigm that employs high-dimensional dynamical systems for information processing. Although biological neuronal networks (BNNs) have been utilized to implement reservoir computing to provide insight into their computation properties, the neurons in conventional cultured neuronal networks are randomly connected, generating atypical dynamics characterized by highly correlated bursting activity not observed in healthy brains. In this study, we used micropatterning technology to fabricate BNNs with modular topology, a structural feature conserved in brain networks, and to understand how the dynamics within non-random networks of neuronal cells are linked to computing. Our study demonstrated that the modular BNN reservoir is capable of classifying both image and time-series data above chance levels. The modular structure in BNN contributes to the increased reservoir computing performance, in line with previous computational models with neuromorphic networks. Combining experiments with biological neuronal network and computational modeling can advance our understanding of computing principles in multicellular neuronal networks.

    In this presentation, we will first introduce our studies aimed at reproducing an evolutionarily-conserved net-work structure in cultured neuronal networks on engineered glass coverslips and CMOS-based high-density microelectrode arrays. We then describe our recent attempts to couple the engineered neuronal networks with external stimulation to reveal their response to noise and spatiotemporally-patterned inputs to show that bioengineering technologies offer novel tools in investigating computational aspects of multicellular networks of biological neurons.

    We have investigated the particle size distribution of nanobubbles (NBs) the nanoparticle tracking analysis method and found that the particle size is discrete and increases by a factor of √2. We interpreted that this peculiar particle size distribution is caused by the fact that NBs of the same size tend to coalesce with each other, and simulated the particle size distribution incorporating this effect, and found that it can generally reproduce the experiment. The results of recent studies on the interfacial structure of NBs will also be presented.

    Phospholipid bilayer is the basic structure of cell membranes. Artificially formed planar bilayer lipid membrane (BLM) has been widely used as a system for the functional analysis of membrane proteins. However, the measurement method has remained unchanged for several decades. Transmembrane voltage is usually used as the input, and the measured transmembrane current is used as the output of the system. In this work, we propose a method to improve the control of the BLM system by applying a voltage parallel to the BLM (lateral voltage) in addition to the traditional transmembrane voltage. The effects of the lateral voltage on the ion-channel-incorporated BLM systems were investigated.

    <p>In this presentation, a new platform based on bio-hybrid membranes will be proposed and discussed in detail. The bio-hybrid membrane is a 2D structure composed of lipid molecules and functional nanomaterials. It has the advantage of lipid bilayer structure, such as flowability, ultrathin thickness and ultrahigh resistance. At the same time, it possesses optical, electrical, magnetic functionality of the nanomaterials. Furthermore, due to the unique molecular packing in the structure, new properties can be discovered from the bio-hybrid membrane. Using the bio-hybrid membrane, we were able to discover unique properties and fabricate high-performance photodetectors and gas sensors. The bio-hybrid membrane introduced here is a flexible and feasible platform for novel nanodevices.</p>

    We have proposed a simple method of generating nano-bubbles (NBs) by a porous alumina film with ordered nano-scaled holes. We have investigated the size distribution of NBs generated by our proposed method using the nano tracking analysis (NTA). We found that the diameter of the NBs is in the range of 50-150 nm and depends on the kind of the gas in NBs.

    Mechanical properties of scaffolds have recently been found to impose strong impact on the behavior of cultured cells. Here, we focused on the effect of scaffold’s elastic modulus on the development of synaptic connections in cultured neurons, and established a novel system for culturing rat cortical neurons on an ultrasolft gel surface with an elastic modulus resembling the brain. Impact of the soft scaffold on the amplitude of synaptic currents and spontaneous neuronal activity, analyzed via patch -clamp recording and fluorescence calcium imaging, will also be presented.

    We fabricated micro gas sensors through the local anodization process. In addition, metal nanoparticles were electrochemically deposited on the sensors and the response characteristics of the sensors were controlled. These results indicate that the local anodization process and electrochemical deposition of metal nanoparticles allow integration of different micro gas sensors in characteristics.

    This paper reviews our recent approaches for a label-free detection of protein-protein interactions which can perform simultaneous protein conformational analysis by using infrared absorption spectroscopy in the multiple internal reflection geometry (MIR-IRAS). Using this method, the target protein was detected in aqueous solution phase based on the peak height of the protein amide I and amide II bands, while discrimination of specific and nonspecific signals is made based on the secondary structure of the target protein. An antigen-antibody interaction on semiconductor surfaces was investigated as a model system, since it is well-known that antibodies largely consist of β-sheet structures. The features of our approach using MIR-IRAS combined with protein secondary structure analysis were discussed in terms of sensitivity, capability of quantitative analysis, and specific/nonspecific discrimination.

  1. Modular Topology Enhances Reservoir Computing Performance in Biological Neuronal Networks

    Sumi Takuma, Yamamoto Hideaki, Katori Yuichi, Ito Koki, Sato Shigeo, Hirano-Iwata Ayumi

    IEICE Proceeding Series 2023/09/21

    More details Close

    Reservoir computing is a machine learning paradigm that employs high-dimensional dynamical systems for information processing. Although biological neuronal networks (BNNs) have been utilized to implement reservoir computing to provide insight into their computation properties, the neurons in conventional cultured neuronal networks are randomly connected, generating atypical dynamics characterized by highly correlated bursting activity not observed in healthy brains. In this study, we used micropatterning technology to fabricate BNNs with modular topology, a structural feature conserved in brain networks, and to understand how the dynamics within non-random networks of neuronal cells are linked to computing. Our study demonstrated that the modular BNN reservoir is capable of classifying both image and time-series data above chance levels. The modular structure in BNN contributes to the increased reservoir computing performance, in line with previous computational models with neuromorphic networks. Combining experiments with biological neuronal network and computational modeling can advance our understanding of computing principles in multicellular neuronal networks.

    In this presentation, we will first introduce our studies aimed at reproducing an evolutionarily-conserved net-work structure in cultured neuronal networks on engineered glass coverslips and CMOS-based high-density microelectrode arrays. We then describe our recent attempts to couple the engineered neuronal networks with external stimulation to reveal their response to noise and spatiotemporally-patterned inputs to show that bioengineering technologies offer novel tools in investigating computational aspects of multicellular networks of biological neurons.

  3. Time-Series Classification in Micropatterned Neuronal Network Reservoirs

    IEICE Proceeding Series 2022/12/12

    More details Close

    Reservoir computing provides a novel framework to understand how the dynamics within biological neuronal networks (BNNs) is linked to information processing. Here, we used micropatterned substrates to fabricate BNNs with modular topology, one of the important structural features of brain networks, and realized a reservoir system with the modular BNN. Using image and time-series classification tasks, we evaluated the reservoir computing properties of the BNN reservoirs. The results show that modularity facilitates the separation between the trajectories of the neuronal responses to different spatial patterns, pointing to the functional advantage of the animals to modular topology within the nervous systems.

    Abstract book of Annual Meeting of the Japan Society of Vacuum and Surface Science 2021

    More details Close

    Phospholipid bilayer is the basic structure of cell membranes. Artificially formed planar bilayer lipid membrane (BLM) has been widely used as a system for the functional analysis of membrane proteins. However, the measurement method has remained unchanged for several decades. Transmembrane voltage is usually used as the input, and the measured transmembrane current is used as the output of the system. In this work, we propose a method to improve the control of the BLM system by applying a voltage parallel to the BLM (lateral voltage) in addition to the traditional transmembrane voltage. The effects of the lateral voltage on the ion-channel-incorporated BLM systems were investigated.

    More details Close

    We have investigated the particle size distribution of nanobubbles (NBs) the nanoparticle tracking analysis method and found that the particle size is discrete and increases by a factor of √2. We interpreted that this peculiar particle size distribution is caused by the fact that NBs of the same size tend to coalesce with each other, and simulated the particle size distribution incorporating this effect, and found that it can generally reproduce the experiment. The results of recent studies on the interfacial structure of NBs will also be presented.

    Abstract book of Annual Meeting of the Japan Society of Vacuum and Surface Science 2020

    More details Close

    <p>In this presentation, a new platform based on bio-hybrid membranes will be proposed and discussed in detail. The bio-hybrid membrane is a 2D structure composed of lipid molecules and functional nanomaterials. It has the advantage of lipid bilayer structure, such as flowability, ultrathin thickness and ultrahigh resistance. At the same time, it possesses optical, electrical, magnetic functionality of the nanomaterials. Furthermore, due to the unique molecular packing in the structure, new properties can be discovered from the bio-hybrid membrane. Using the bio-hybrid membrane, we were able to discover unique properties and fabricate high-performance photodetectors and gas sensors. The bio-hybrid membrane introduced here is a flexible and feasible platform for novel nanodevices.</p>

    Mechanical properties of scaffolds have recently been found to impose strong impact on the behavior of cultured cells. Here, we focused on the effect of scaffold’s elastic modulus on the development of synaptic connections in cultured neurons, and established a novel system for culturing rat cortical neurons on an ultrasolft gel surface with an elastic modulus resembling the brain. Impact of the soft scaffold on the amplitude of synaptic currents and spontaneous neuronal activity, analyzed via patch -clamp recording and fluorescence calcium imaging, will also be presented.

    We aim to develop a drug screening system based on a reconstitution system in which ion channels are embedded in an artificial lipid bilayer membrane (BLM). We have been developing stable BLMs based on silicon (Si) microfabrication. We previously reported on efficient incorporation of ion channels in BLMs. Here we applied this system to a cell-free synthesized hERG channel and tried to quantify drug side effects on this channel.

    We have proposed a simple method of generating nano-bubbles (NBs) by a porous alumina film with ordered nano-scaled holes. We have investigated the size distribution of NBs generated by our proposed method using the nano tracking analysis (NTA). We found that the diameter of the NBs is in the range of 50-150 nm and depends on the kind of the gas in NBs.

    Lateral bias印加のための電極内蔵型支持体を作製し,この支持体中での膜形成について検討した.ベース素材としてはシリコン(Si)チップとテフロンフィルムの2種を比較した.その結果,いずれの素材においても脂質二分子膜の形成が可能であったが,Siチップでは脂質分子のみで膜形成が可能であるのに対し,テフロンフィルムでは孔周辺にヘキサデカンの塗布が必要であった.次に,これらの膜系にLateral biasを印加したところ,Siチップ系では交流電圧が,テフロンフィルム系では直流電圧が低ノイズ計測に適していることが分かった.さらに,形成した脂質二分子膜中にフラーレン誘導体(PCBM)や生体イオンチャネルを包埋し,Lateral biasの効果について検討した結果,PCBMドープ膜が示す膜貫通方向の光誘起電流や,電位依存性Naチャネルが示す膜貫通電流が,ともにLateral biasによって増大する現象を見出した(Faraday Discussion, in press, 2022).しかし,その作用メカニズムは不明であったため,平面脂質二分子膜に対する蛍光観測系を立ち上げ,Lateral biasの作用メカニズムについて蛍光プローブを用いた検討を進めた.また,上述の電極内蔵型支持体では,Lateral biasの印加に伴って電極材料のチタン(Ti)が酸化チタン(TiO2)へと変化するという課題も判明したが,Ti電極を白金(Pt)で被覆することによって酸化を防止できることも分かった.来年度は,電極内蔵型支持体の量産化も進め,メカニズムの検討および応用探索を加速化していく予定である.

    脂質二分子膜の膜内に,膜に平行な方向に電圧を印加するための電極内蔵型膜支持体を,シリコン(Si)チップおよびテフロンフィルムの2種類の素材をベース材料として作製した.これらの支持体中での脂質二分子膜形成が,電極の存在によって影響を受けないことを確認した後,膜平行電圧印加に伴う膜電気特性の変化について,ノイズ電流レベル,膜抵抗,電気容量の観点から評価した.さらに,形成した脂質二分子膜中にナノ材料や生体イオンチャネルを包埋し,これらのハイブリッド膜に対する膜平行電圧の効果について検討した.その結果,フラーレン誘導体のPCBMドープ膜が示す膜貫通方向の光応答電流や,電位依存性Naチャネルが示す膜貫通電流が,ともに膜平行電圧の印加によって変調・増強されることを見出した(Faraday Discussion, in press,2022).この膜平行電圧による膜貫通電流の増強作用や,PCBMドープ膜の光応答電流については,どちらも興味深い現象ではあるが発生メカニズムが不明であったため,2021年度は,脂質二分子膜系に対する蛍光測定系を立ち上げ,これらの現象の作用メカニズムについて蛍光プローブを用いて検討した.また,上述の膜支持体では,チタン(Ti)を電極材料として用いていたが,膜平行電圧の印加に伴って,コンタクト部位が酸化チタン(TiO2)へと変化しやすいことも分かってきた.そこで,Ti電極上への白金(Pt)コーティングを検討した結果,電極の酸化防止に効果的であった.一方,TiO2はそれ自体が魅力的なチューブ状ナノ構造体であり,このナノチューブを利用したガスセンサーの構築(Langmuir, 2021)やナノバブル生成への応用についても検討した(Sensors and Actuators: B, Chemical, in press).

    We have proposed a novel flexible sensor in which microwire-embedded β-phase poly(vinylidene fluoride) (PVDF) films are utilized. The polarization of PVDF was controlled by using thiol-modified gold surfaces that we developed in this study. We succeeded in detecting the pressure changes of the sensor in one-dimensional direction or two-dimensional plane, in accordance with a spatial resolution of 200 micrometers. Our proposed sensors would be very useful for practical realization of various wearable devices such as tactile sensors and sphygmometers.

    In recent years, the risk evaluation of potential drug side effects to the heart is indispensable in drug discovery, and it is highly desirable to construct an artificial system for this evaluation. In this study, we tried to develop a screening platform for potential drug side effects based on artificially formed bilayer lipid membranes (BLMs) that can express action potentials. However, we faced an issue of a low efficiency in incorporation of ion-channels that are necessary for generation of action potentials. To address this issue, we investigated the process of ion channel incorporation and found that application of appropriate centrifugal forces during the incorporation process lead to a dramatic enhancement of the incorporation probability from ca. 6% to ca. 70%. We also investigated development of high-throughput assay systems for the ion channels and succeeded in simultaneous recordings of hERG channel activities in BLM systems.

    This project aimed to elucidate the active state created by a plurality of membrane proteins and surrounding lipid molecules, and relating phenomena using a cell membrane model system. We reconstructed ion channel proteins that were obtained from cultured cells and cell-free protein synthesis system, in supported lipid bilayers (SLBs). Distribution and molecular structures of lipids and membrane proteins were observed by fluorescence microscopy and atomic force microscopy. We propose a model to explain the mechanism of reconstitution by clarifying the role of cell membrane derived components in SLB. We revealed that the role of intra-membrane microdomains in the reconstitution process. It is revealed that the molecular orientation of the channel protein expressed by cell-free synthesis varies depending on the reconstitution process.

    We have proposed a simple method of generating nano-bubbles (NBs) by a porous alumina film with ordered nano-scaled holes. We have investigated the size distribution of NBs generated by our proposed method using the nano tracking analysis (NTA) and the semiconductor surface cleaning effect of NBs using infrared absorption spectroscopy in the multiple internal reflection geometry (MIR-IRAS) and a scanning electron microscope (SEM). We found that the diameter of the NBs is in the range of 50-150 nm and depends on the kind of the gas in NBs. When a Si surface covered with an organic film was exposed to NBs in water, absorption bands originated from the film significantly decreased their absorption intensities. In addition, SEM images showed that after exposure to NBs, there appeared a number of circular traces where no carbon contaminations were observed. These observation clearly indicate the surface cleaning effect of NBs.

    This study aims at realization of single-electron tunneling in lipid bilayers as a new sensing principle. We first examined incorporation of nanoparticles into lipid bilayers and found that only very small nanoparticles could be incorporated into self-standing bilayer lipid membranes. We next examined simulation on single-electron effects of aligned nanoparticles and revealed that observable single-electron effects would be possible even at room temperature. In addition, we have established fabrication procedures for silicon chips with wired metal electrodes. We would like to combine these techniques to realize single-electron tunneling in lipid bilayers and apply to highly sensitive biosensors to demonstrate a novel sensing principle.

    TiO2 nanotube micro gas sensors were fabricated using the local anodization technique that is a hybrid process between photolithography and anodization technique. Catalytic metal nanoparticles such as Pt and Pd were electrochemically deposited on TiO2 nanotube surface homogeneously. Pt nanoparticles improved the sensitivity about 300 times. On the other hand, the response characteristics to hydrogen and carbon monoxide strongly depended on deposited catalytic metal nanoparticles. This result indicates that micro gas sensors with different response characteristics can be integrated on a chip and multicomponent gases can be simultaneously monitored by analyzing response characteristics.

    Human brain is a complex, hierarchical system comprised of 10 billion neurons. By engineering a simple neuronal network in vitro that mimics the in vivo architecture and functions, a novel system for studying of the dynamical properties of the neuronal networks in the brain will become available. In the current project, we developed a series of surface micromodification techniques for fabricating "template" surfaces for neuronal cell patterning. We then evaluated the spontaneous activity of the micropatterned neuronal networks via fluorescent calcium imaging. A simulation model of neuronal networks based on a biophysical model was also developed to theoretically investigate activity modulation in micropatterned networks.

    We have developed biosensors for bio-nanospace “synapses” and investigated their application to measurements in brain. We combined amperometric glutamate microsensor and recording of field excitatory postsynaptic potentials (fEPSPs) as a new method for analyzing relation between presynaptic and postsynaptic activities. Although it was found that electric stimuli and evoked fEPSPs induced a capacitive transient current at the microsensor, we proposed a method to extract a faradaic signal from the observed currents. Then we applied this method to long-term potentiation (LTP) in the hippocampus. It was found that the level of the extracellular L-glutamate during tetanus stimulation was significantly related to LTP induction. Thus, our simultaneous recording method for pre- and post-synaptic activities can be a useful tool for neurosciences. We also investigated efficient construction of lipid bilayer-based sensor utilizing ion channel as a sensory element for neurotransmitters.

    The purpose of this study is development of an atomic force microscopy (AFM)-based method for manipulating single ion-channels through the combination of AFM and recently reported stable bilayer lipid membranes (BLMs). The final goal is that isolation of ion channels from cell membranes and subsequent incorporation of the channel into free-standing bilayer lipid membranes is made by AFM. We started with design of a solution cell and construction of cell lines expressing ion channel proteins. In addition, further improvement of stable BLMs was also achieved by coating the microfabricated silicon chips with insulator layers. We succeeded in formation of stable BLMs with electrical properties suitable for recording single-channel activities of biological ion channels

    Artificial bilayer lipid membranes (BLMs)have attracted attention as a platform for highly sensitive biosensor and drug screening systems. However, the instability of BLMs hinders their wide range of applications. In the present study, we have succeeded in preparation of stable free-standing BLMs through the combination of silicon microfabrication and BLM formation. The BLMs were not broken by applying a constant voltage of ±1 V. The membrane lifetime was 15-45 h with and without incorporated gramicidin channel. The BLMs with incorporated channel showed tolerance to repetitive solution exchanges. Such stable membranes enable analysis of channel functions under various solution conditions from the same BLM, which will open up variety of applications including a high throughput drug screening for ion channels.

    本研究では、ナノメートルスケールのグルタミン酸センサー構築のための基礎検討を目的としている。当初は、酵素グルタミン酸オキシダーゼに基づくセンサー設計を予定していたが、入手可能なグルタミン酸オキシダーゼにはグルタミナーゼが混入しており、脳内に高濃度に存在するグルタミンとの識別が困難であることが判明した。そこで感応素子としては、酵素に比べてより高感度かつ高速応答が見込めるグルタミン酸レセプターチャネルを用いることにした。昨年度は、感応素子のグルタミン酸レセプターのマトリクスとなる平面脂質二分子膜のナノ空間への作製とその安定化を行ったが、平成20年度は、実際に、ラット脳より抽出したグルタミン酸レセプターを膜中に包埋し、そのチャネル応答の記録を試みた。半導体微細加工技術を用いて作製したナノスケールの孔や、ポーラスアルミナナノ構造体中で脂質二分子膜の形成を行い、その中に抽出したグルタミン酸レセプターチャネルを包埋した。この膜のグルタミン酸応答を評価したところ、活性は見られたものの他のチャネルタンパクが混在しており、純度を高めるためのさらなる精製が必要であることが分かった。現在、その精製法について検討中である。また、安定化脂質二分子膜作成の基礎知見を得るために、表面赤外分光を用いた分光学的検討も行い、多重内部反射型赤外分光法(MIR-IRAS)を用いて、シリコン基板上のアガロース支持二分子膜を観察し、脂質溶液から自発的に脂質二分子膜が形成していく過程を、標識を用いることなくその場観察することに成功した(投稿中)。その他、シリコン基板表面上における種々の生体分子反応(DNAのハイブリダイゼーション、抗原抗体反応、細胞死)をMIR-IRASを用いて非標識でその場観察することに成功した。

    In this research, we have developed m situ real-time monitoring method for cell dynamics on the basis of infrared spectroscopy with the multiple internal reflections (MIR-IRAS). Our research projects were focused on (1) development of IRAS method for in situ monitoring of cell growth, (2) development of non-label IRAS detection of cell death and its application to cytotoxic assay. In addition, we also examined non-label detection of biomolecular interactions, such as (3) antigen-antibody interactions and (4) DNA hybridization both in solution phase and at the silicon surfaces. For the development of the real-time monitoring of cell dynamics, we started with construction of cell culture condition in a FTIR sample room. The temperature and humidity in a cell chamber placed in the FTIR sample room was controlled to be 37 °C and >80%, respectively. Since the sample room needs to be purged with air which was free from water and carbon dioxide vapor, a humidified gas mixture containing CO_2 was introduced to the chamber through silicone tubes. By using this apparatus, we have confirmed the cell viability and proliferation of HL-60 cells after 24-h incubation in the chambers. Then the cytotoxic effect by Tween20 was in-situ monitored with MIR-IRAS. It was demonstrated that the cell death can be monitored in-situ by analyzing the amide II peak intensity. In addition, we succeeded in real-time monitoring of the dynamic processes upon apoptosis induction by using MIR-IRAS. We also examined label-free detection of antigen-antibody interactions and DNA hybridization and demonstrated that MIR-IRAS is particularly useful for discriminating specific and non-specific adsorption by careful analysis of spectral features. Thus our method can be applied to in-situ monitoring of various cellular events as well as individual biomolecular interactions as non-label detection method for high-performance cell-chips and bio-chips.

    平成21年,厚生労働省は,全候補薬品に対し,心筋のhERGチャネルに対する安全性をin vitroでのチャネル電流側定によって評価することを義務付けた.このチャネルは薬物に非常に敏感で,死亡例を含む重篤な副作用を数多く引き起こしたからである.このような背景を受け,現在,イオンチャネルに対する高効率な薬物スクリーニング系への重要が高まっている.人工脂質二分子膜は,薬物スクリーニング系のプラットフォームとして期待が高いが,機械的強度が極めて低く,その発展の障害となっていた.我々は最近,ナノ構造体や半導体加工技術と脂質二分子膜形成の融合により,機械的強度の高い脂質二分子膜の構築に成功した.さらに作製したチップを低誘電率の絶縁材料で被覆することにより,電気特性の問題(ノイズ電流および過渡応答特性)を解決した.次の段階としては,この安定化脂質二分子膜にイオンチャネルを組込み,薬物スクリーニングのためのイオンチャネルチップへと展開することであるが,安定な脂質二分子膜ではチャネルの組込確率が低いという新たな課題に直面している.そこで,本研究では,安定化人工脂質二分子膜へのイオンチャネルの効率的組込法について検討し,これに基づいて,チャネル包埋二分子膜をアレイ状に並べたイオンチャネルチップを,hERGチャネルを対象に構築する.hERGチャネルアレイに基づく新薬開発のための新規な副作用評価ツールとして提案する.

    イオンチャネルは創薬における主要ターゲットの一種であり,イオンチャネルの薬物応答を高効率に評価する方法の開発が望まれている.細胞膜構造を模した人工平面脂質二分子膜にイオンチャネルを包埋した再構成系は,化学的制御系においてチャネルへの薬物作用が評価できる特徴をもつ.本研究では,申請者が最近報告した安定化人工脂質二分子膜に効率良く生体イオンチャネルを包埋するための化学的および物理的手法の検討を行い,イオンチャネル包埋脂質二分子膜センサーを構築するための基礎とすることを目的としている.イオンチャネルはリポソームに包埋された状態で抽出されるため,イオンチャネルの包埋促進のためには,リポソームの二分子膜中への膜融合を促進する必要がある.そこで本研究では,膜融合促進ペプチドや誘電泳動などを用いて一過性の化学的および物理的摂動を二分子膜に与えることにより膜融合の促進について検討し,安定性の高い膜ならではのタンパク質組み込み法を提案する.
