Graphene for surface enhanced Raman scattering (SERS) molecular sensors
In this paper, graphene for SERS molecular sensors is reviewed along with a report of new innovations. Arrays of silver nanoparticles were selectively deposited on copper, on which discrete graphene domains had been synthesized. Closely spaced silver nanoparticles create strong local electric fields by means of laser induced plasmonic coupling. Signal intensity measured from Raman scattering of low concentration of R6G probe molecules was enhanced by more than eight orders of magnitude in comparison with that without closely spaced silver nanoparticles surrounded by graphene.
