| Outline of Final Research Achievements |
With the aim of developing a microfabricated chemical sensor chip combined with African clawed frog (Xenopus laevis) oocytes expressing chemical receptors by genetic engineering, I made a compact fluidic device integrated with microelectrodes that could measure the cells’ responses to chemical stimuli. Plural Xenopus oocytes could be trapped one-by-one in the fluidic device along with the flow at the same time as the electrodes’ automatic connection to each oocyte. The cell-based chemical sensor chip successfully detected a target chemical substance. Furthermore, for odorant detection using Xenopus oocytes expressing olfactory receptors, I additionally attempted to construct an odorant solubilization system based on a microfluidic device for gas-liquid mixing. The fluidic channel was filled with porous material such as filter papers. In this project, I succeeded in development of a Xenopus oocyte array fluidic device with microelectrodes for electrophysiological measurement.
