The capability of scanning tunneling microscopy to image individual molecules intercalated under graphene is demonstrated for fullerenes. The C60 molecules become visible through the graphene carpet grown on Ni(111) due to an extremely strong bias-dependent spectroscopic contrast. Its origin is a blocking of the chemical interaction between graphene and its substrate by the fullerenes.
