Paper Abstract

In this paper the mechanism responsible for the sensitivity enhancement is theoretically analyzed. The thickness of the coupling film is optimized to obtain better sensor performance. It is verified that the result of present method offers more sensitive detection than that of the conventional SPR technique does. The biosensor applications for this technique are also discussed.
