- •
The present study investigates the performance parameters of SPR biosensor by taking the advantage of air gap as dielectric between prism and silver layer along with good adsorption properties of graphene.
- •
It is observed that the overall performance of the proposed biosensor is improved by introducing the air gap.
- •
Also, It is observed that performance parameters of proposed SPR biosensor affected due to chemical potential and temperature of graphene.
