The present invention relates to coating with a graphene single layer film the conductive surface of an atomic force microscope tip. The process of coating the conductive surface with graphene consists in three steps: first, immobilization of the tip on a Silicon block as a base using a thin film of Poly-methyl methacrylate (PMMA) in between. Then, the solid PMMA/AFM tip/PMMA/Silicon block was used as target substrate on which it is transferred the graphene sheet. Finally, it is removed the different PMMA layers using Acetone. Once PMMA is removed, the graphene is completely attached. The resulting tip is perfectly coated with graphene, and therefore much more resistant to both high currents and frictions than commercially available metal-varnished CAFM tips, and also to much larger lifetimes and more reliable imaging due to a lower tip-sample interaction.
