This research paper introduces the advantage of using graphene as a sensitivity enhancing material for the Surface Plasmon Resonance (SPR) Biosensor. Fresnel's four layer model has been used here for analyzing the performance parameters of SPR biosensor. The analysis shows that Surface Plasmon Resonance Frequency (SPRF) increases with the increasing concentration of target molecule for every graphene layer. It is found that the sensitivity curve for different graphene layer with respect to conventional SPR biosensor is non-linear. How the sensitivity increases with increasing graphene layer was studied in this work. The basic polynomial fitting is used and found that sensitivity increases nonlinearly with the increasing layers and the degree of nonlinearity also increases.
