46/85 Cell fixation in the semi-closed microchip


To realize the stable observation during the solution exchange and cell culture, fixation of cells is needed. In this research, we use the thermo sensitivve solution, PNIPAAm. To use the PNIPAAm, Indium Tin Oxide electrodes were fabricated as heaters in the bath as shown In this photograph. By fabricating this electrodes, cells can be fixed by the thermo sensitive gel when applying a voltage to the ITO electrode.
