In this paper, surface plasmon resonance biosensor consisting of functionalized gold surface by graphene and microfluidic channel is fabricated. Graphene is synthesized by chemical vapor deposition method and transferred to the gold substrate using polymer. The results obtained from the Kretschmann configuration show that the biosensor based on graphene functionalized gold is more sensitive than the bare one in biomolecules adsorption.
Keywords: Biosensor, Graphene, Kretschmann configuration, Surface plasmon resonance
