Abstract :
We have designed and fabricated surface plasmon resonance (SPR) sensor with metallic nano-structure to improve sensitivity. We have fabricated the metallic nano particles with rapid thermal annealing process to realize the proposed nano-plasmonics SPR sensor. In experiments, we confirmed the sensitivity of the proposed nano-plasmonics SPR sensor is 93.75 degree/RIU while that of conventional SPR sensor is 84.76 degree/RIU.
