Bio-compatible and highly sensitive two-dimensional plasmonic sensor

摘要

We propose a novel bio-compatible two dimensional plasmonic sensor with array of ring and the hole structure on an optically thick gold film for biochemical sensing. We use finite-difference time-domain simulation for design and calculation of sensitivity in the near-infrared region. The bio-compatible and cheap plasmonic glycerol sensor with high sensitivity by interferometer style as a motif in the sensor's structure. The proposed sensor can be applied as highly sensitivity sensor with a good linear response under different glycerol concentrations.
