| Abstract: | In this study, a molybdenum disulfide (MoS2) based surface plasmon resonance (SPR) biosensor is proposed. The reflectance curves for the proposed SPR biosensor are analyzed and compared with the graphene based and the conventional SPR biosensors. It is observed that the performance parameters of the proposed biosensor- sensitivity, detection accuracy, and the quality factor are enhanced by the utilization of the adsorption property of MoS2 for monolayer and bi-layer MoS2. Also, the effect of increasing the number of layers of MoS2 on the reflectance curve is analyzed and compared. |
