AuNPs under graphene

Gold nanoparticles on an ITO surface under a layer of graphene. The structure of the ITO, which is transparent in optical microscopes, is visible in blue. The nanoparticles are clearly visible through the very thin layer of graphene.

Pictured using a FEI Nova NanoSEM. The full width of the pictures is about 1 micrometer.
