Abstract
This paper numerically presents a highly sensitive surface plasmon resonance (SPR) graphene-based biosensor by taking high adsorption efficiency of graphene into consideration. The pi-stacking interaction between carbon-based hexagonal structure of graphene with carbon-based ring biomolecules such as single-stranded DNA is the key factor behind this efficiency. Graphene layers added to a conventional copper SPR biosensor causes a drastic sensitivity enhancement. In comparison to conventional SPR sensors this produces a larger change in the refractive index at the metal-dielectric interface. The light reflection coupled into a SPR mode propagating along a coppergraphene layer is calculated and compared to a conventional SPR sensor. The proposed SPR sensor could then not only be applied for highly sensitive but also for cheap DNA-biosensor.
