Graphene on split ring resonator arrays, as described on page 151 by G. Sarau et al., represents a novel and tunable platform for gaining a basic understanding of surface-enhanced Raman scattering (SERS) effects. The Raman enhancement of graphene proves the strong plasmonic coupling between graphene and the metamaterial resonances excited by incident, photoluminescence, and Raman light. This opens the way towards an advanced SERS substrate for high-sensitivity detection of molecules attached to graphene.
