This paper describes the effect of adding MoS2 layers to surface plasmon resonance biosensors based on the hybrid structure of Ag nanoparticles and graphene using a spectacular interrogation mode. The proposed sensors are designed from MoS2 material as biomolecular recognition elements. The Ag is the ideal metal for plasmon thanks to its low optical frequency loss. The results show that using a 14.30 nm MoS2 layer leads to an increase of the plasmon resonance of more than 500 nm at 1066.67 nm due to localized surface plasmon resonance (LSPR) in the grooves that amplifies the interaction of light and MoS2. We have studied the performance of the proposed biosensors in terms of sensitivity using multilayers of MoS2. We have obtained very high sensitivity with an increase of 49.37. This characteristics should make the proposed biosensors a preferred choice for biosensors applications, compared to other contemporary biosensors. © 2018 IAMOT.
