Paper Abstract

In this work the sensitivity of graphene and sulfide coated biosensors is analyzed in details by an efficient frequency domain finite element method. The proposed sensors are designed by introducing a thin film sulfide coating over a bimetallic surface plasmon resonance biosensor composed by gold and silver. The sensitivity of the proposed sensors can be highly enhanced by introducing the top thin layers. The influence of several sulfide composites in combination with the graphene layer is tuned and optimized by adjusting their optical and geometrical parameters.
