| Outline of Final Research Achievements |
The aim of this research is to provide a platform for the membrane protein analysis, where the function of membrane proteins is detected not directly by measuring the ion channel current, but by utilizing cell-mimetic microwells equipped with ion sensitive field effect transistors. In this research period, FET was fabricated on silicon substrate, and fabrication of microwell structure consisting of SiN/SiO2, which has the same size as a cell, was made on top of FET. Furthermore, theoretical calculations were performed on the microwell structure sealed with the lipid membrane. We obtained useful knowledge about the optimal combination of the substrate surface and the lipid membrane composition in this device structure.
