The Optical Biosensor based on Surface Plasmon Resonance (SPR) are an important component in Bio-photonic field. These biosensors are applicable for investigation of protein binding, enzymes detection and DNA hybridization for medical diagnostics. In this paper, the optical biosensor based on SPR is designed by using nanocomposite- MoS2 –graphene layered structure. We investigated the presence of the Au nanocomposite layer on the biosensor sensitivity. Also, our results show that the biosensor with nanocomposite layer thickness of 30 nm, 9 layer of MoS2 and 3 layer of graphene have the maximum sensitivity 106.16 deg/RUI.
 
Keywords: Biosensor, Nano-composite, Sensitivity, Surface Plasmon Resonance.
