Abstract :
The optical sensitive protein ldquobacteriorhodpsin (BR)rdquo can be applied to a detection part of a high-speed recognition sensor for the moving body. We fabricated the CNTFET on which the BR is directly functionalized by biotin-avidin method. For the BR- CNTFET device, optical response is observed at start point and end point of irradiation of white light. It is due to the structural relaxation of BR and the movement of proton in BR on the CNTFET.
