Abstract
In this paper we have proposed a novel long-range surface plasmon resonance sensor (LRSPR) based on LiF and graphene having single metallic layer. Angular interrogation method is used for the detection of biomolecules. Imaging sensitivity for conventional SPR sensor and LRSPR sensor has been calculated and compared. Also, the imaging sensitivity is analyzed with increasing layers of graphene. In our result imaging sensitivity of LRSPR sensor with single layer of graphene is found to be 867 RIU−1 while for the conventional SPR is 308 RIU−1, which shows around three times enhancement. The detection accuracy of LRSPR with single layer of graphene is found to be 5.94 Deg−1, which also shows around three times improvement than that of conventional SPR.
