Graphene-based plasmonic nanostructures were investigated for highly sensitive Raman detection of aromatic compounds. aromatic compounds with benzene rings were preferentially adsorbed on graphene through π-π interactions in the proximity of metallic nanostructures. Raman enhancement factor varied significantly depending on the number of graphene layer, and the highest enhancement was obtained for the monolayer graphene substrate due to the strongest field confinement in the vicinity of metallic nanostructures.
