In this study, a surface plasmon resonance (SPR) based fiber optic sensor coated with graphene is described. Graphene synthesized by chemical vapor deposition (CVD) is transferred on sensing area of an optical fiber. The sensor principle is based on change in SPR according to the different dielectric constants of analytes. This sensor is evaluated with biotinylated DNA lattice and protein Streptavidin. To the best of our knowledge, this is the first ever attempt to incorporate graphene as the replacement of conventional metal films. The preliminary result is encouraging results towards the analytes with excellent sensitivity. We believe that the use of graphene as a metallic film in SPR sensor will lead new path in the field of biochemical sensing technology.
