A paper that will appear in today's issue of Science describes the use of an atomic force microscope (AFM) to produce graphene features as narrow as 12nm on an insulating surface of graphene oxide.

Their first approach, using a scanning tunneling microscope, provided images that were too fuzzy. They decided to try the noncontact atomic force microscopy (nc-AFM) technique.
