Outline of Final Research Achievements

This study presents the molecular electrochemical switching element based on molecular diffusion and electrochemical reaction. The element acts like a transistor. The elements were incorporated into a small chip device, and the device was characterized. The device was applied to evaluation of cell differentiation of embryonic stem cells and respiration activity of cancer cells. In addition to them, the novel electrochemical imaging system was developed using CMOS-based electrode arrays. By using the device, multiple analytes were electrochemically imaged at the same time.
