The combination of gold nanoparticles and graphene veiling is a novel approach to fabrication of active substrates suitable for Surface Enhanced Raman Spectroscopy (SERS). Graphene can serve as a pin-hole passivation layer, which prevents plasmonic nanostructures from oxidizing. The level of the contact between Au particles and graphene plays a significant role in the sensitivity of SERS. Therefore, it is important to know the way a graphene membrane veils a single nanoparticle or a cluster of such nanoparticles.
