受賞対象となった研究の内容

This study has developed metal oxide nanoparticles as the electrochemical sensor for dopamine and acetylcholine detection. The microelectrodes with metal oxide nanoparticles were applied onto a flexible polyimide substrate for performance evaluation in vitro and in vivo. Microelectrode has prepared by mixing metal oxide nanoparticles hematite iron oxide (Fe2O3) and copper oxide (CuO), and MWCNTs were undergoing hydrothermal. The electrochemical performances of modified microelectrodes were evaluated by fast-scan cyclic voltammetry which was conducted in dopamine and choline acetate. The modified microelectrode observed a linear response of dopamine and acetylcholine with high sensitivity. This new modified detector can offer outstanding opportunities to overcome drawbacks in conventional detectors and promise to integrate with the CMOS imaging sensor.
