| Outline of Final Research Achievements |
In this project, a novel optical biosensor using the SOI (silicon-on-insulator) photodiode with SP (surface plasmon) antenna has been studied to realize the silicon-based integrated circuits, higher power utilization efficiency of light source, and simpler optical system.
We could obtain the major results including that (1) a new evaluation method has been proposed to increase the refractive index sensitivity, and (2) the biosensor system has been developed to treat solutions. In our proposed system, the comparable refractive index sensitivity with that of the other optical biosensor system has been obtained, and it may be further enhanced by reducing the influences of the light source intensity fluctuations, the solution temperature fluctuations, the system vibrations, and so on.
