Wang, Ling. "Microchannel enhanced neuron-computer interface: design, fabrication, biophysics of signal generation, signal strength optimization, and its applications to ion-channel screening and basic neuroscience research." Doctoral thesis, Universitat Politècnica de Catalunya, 2011. http://hdl.handle.net/10803/52810.
In this present work, we used microfabrication techniques, numerical simulations, electrophysiological experiments to explore the feasibility of enhancing neuron-computer interfaces with microchannels and the biophysics of the signal generation in microchannel devices. We also demonstrate the microchannel can be used as a promising technique for high-throughput automatic ion-channel screening at subcellular level. Finally, a microwell-microchannel enhanced multielectrode array allowing high signal-to-noise ratio (SNR), multi-site recording from the low-density hippocampal neural network in vitro was designed, fabricated and tested. First, we demonstrate using microchannels as a low-cost neuron-electrode interface to support low-complexity, long-term-stable, high SNR extracellular recording of neural activity, with high-throughput potential. Next, the biophysics of the signal generation of microchannel devices was studied by experiments and numerical simulations. Based on the results, we demonstrate and rationalize how channels with a length of 200 μm and channel cross section of 12 μm2 yielded spike sizes in the millivolt range. Despite the low degree of complexity involved in their fabrication and use, microchannel devices provided a single-unit mean SNR of 101 76, which compares favourably with the SNR obtained from recent developments employing CNT-coated electrodes and Si-NWFETs. Moreover, we further demonstrate that the microchannel is a promising technique for high-throughput automatic ion-channel screening at subcellular level: (1) Experimental data and numerical simulations suggest that the recorded signals are only affected by the membrane patches located inside the microchannel or within 100 μm to the microchannel entrances. (2) The mass transfer of chemical compounds in microchannels was analyzed by experiments and FEM simulations. The results show that the microchannel threaded by glial and neural tissue can function as fluid/chemical barrier. Thus chemical compounds can be applied to different subcellular compartments exclusively. Finally, a microwell-microchannel enhanced MEA (MWMC-MEA), with the optimal channel length of 0.3 mm and the optimal intrachannel electrode position of 0.1 mm to the nearest channel entrance, was proposed based on numerical simulation and experiment results. We fabricated a prototype of the MWMCMEA, whose through-hole feature of Polydimethylsiloxane film (PDMS) was micromachined by reactive-ion etching. The low-density culture (57 neurons/mm2) were survived on the MWMC-MEAs for at least 14 days, from which the neuronal signal with the maximum SNR of 142 was obtained.

Parkinsons sjukdom drabbar 10 miljoner världen över, där 40% av patienterna utvecklar en associerad psykos vilket har visats vara en av de största stressfaktorerna för deras vårdgivare och är även förknippat med en högre dödlighetsgrad. Denna situation förvärras av det faktum att de vanliga antipsykotiska drogerna kan förvärra många av de motoriska symptom som utgörs av Parkinsons sjukdom och det finns i dagsläget enbart en enda kommersiell drog som kan dämpa bägge symptom samtidigt. Detta problem frammanar vidare utveckling av nya läkemedel som kan behandla dessa symptom, som innebär att de först måste testas på försöksdjur. En komplikation som uppstår i relation till detta är svårigheten att utvärdera om läkemedel har någon terapeutisk effekt på de psykotiska tillstånden, enbart genom att observera försöksdjurens beteenden, och en pålitlig biomarkör krävs istället. En lösning kan dock finnas i det faktum att psykotiska tillstånd karaktäriseras av en reducerad förmåga för olika hjärnområden att koordinera genom neural synkronisering vilket demonstreras av ‘steady- state’ responser. Detta föreslår att ett mått på graden av koordineringsförmåga kan agera som en möjlig biomarkör för psykotiska tillstånd. Genom att konstruera ett MATLAB-program kunde vi analysera graden av synkronicitet mellan hjärnstrukturer, under den auditiva steady- state responsen i råttor som hade blivit ensidigt lesionerade genom 6-Hydroxiddopamin modellen av Parkinsons sjukdom, före och efter administration av den psykotomimetiska drogen MK801. Dessa råttor hade blivit kroniskt implanterade med 128 elektroder vilket möjliggjorde att vi kunde mäta styrkan i koherens i den lokala fält potentialen mellan limbiska strukturer, som är associerade med auditiv processering, vilket möjliggjorde identifiering av3dessa strukturers synkronicitet. Vår data demonstrerar att koherensen minskade under det psykotiska drogtillståndet för limbiska strukturer både i den intakta och den lesionerade hjärnhalvan. Detta är en vidare demonstration av att koherensnivåer kan agera som en biomarkör för det psykotiska tillståndet, liksom att vår mjukvara kan nyttjas som ett verktyg för att utvärdera nya läkemedels behandlingsförmåga på Parkinsons psykos.

Electrochemical detection is one of the most versatile and senesitive detection methods used in flow injection and liquid chromatography. Among the various electrochemical techniques applied, amperometric detection, due to the inherient high selectivity and low detection limit, is the most freqently used method. To improve the function of the amperometric detection, varios type of multielectrode detection system have been develope. This paper were divide to three parts. The subject of first part is about the 32-microband electrode array detection system for liquid detection system for liquid chromatography analysis. With this electrode array, both the oxidation and reduction three-dimensional hydrodynamic chromatovolatmmograms of a reversible reaction can be obtained in a single chromatographic run. The versatility of this electrode array was demonstrated by running solutions containing various phenolic compounds with FIA and HPLC system. The subject of the second part is the apllication of a four-material electrode array for flow injection analysis. Difference compounds response to difference material electrode, for a simple sample, the detection system can analsis four compounds at the same time without separation procedure. The subject of the third part is the apllication of a four-material electrode array for liquid chromatography analysis. For a complex sample, there may be more than one compound can resonpse at the same material electrode, to analysis all the componensts in sample, the components were separate by liquid chromatographic column, some un-resolve chromatographic peaks were resolve by difference material electrode.

In this study, a light addressable microelectrode array (LA-MEA) chip and multichannel recording system has been developed to measure electrophysiological signals of neural cells. A sputtered indium tin oxide (ITO) film on a glass is to substitute for metal electrodes and leads in this LA-MEA chip. Hydrogenated amorphous silicon (a-Si:H) is then deposited above the ITO layer and serves as a photoconductor layer. Vertical cavity surface emitting laser (VCSEL) is used as light source and is structured in 8 by 8 arrays with a distance of 200 μm to each other. Each ITO electrode on the chip is addressed by the corresponding VCSEL diode. Meanwhile, the material property of micro-electrode embedded on LA-MEA chip is verified to investigate the optimal fabrication parameters. The result shows the photoconductor micro-electrode of LA-MEA system possesses higher impedance but neural signals are accessible in this system. The specific neural precursor cell line, PC-12, is used in our experiments to measure the electrophysiological signals.
