| description | This paper theoretically presents an improved sensitive surface plasmon resonance (SPR) biosensor using multilayer graphene with angular modulation. Metal thin film functionalization with graphene leads to an enhanced sensitive biosensor. This is due to pi-stacking interaction between carbon-based hexagonal structure of graphene and carbon-based ring biomolecules which increase biomolecule adsorption in the graphene layers. In comparison to conventional SPR sensors this produces a large change in the local refractive index at the sensor surface. The light reflection coupled into a SPR mode propagating along a silver-graphene interface is calculated and compared to a conventional silver-based SPR biosensor. The comparison result shows the improvement in sensitivity of biosensor. |
