Abstract

This document describes graphene-containing platelets and methods of exfoliating graphene from a surface. The method comprises facilitating exfoliation by treatment with proteins. In an embodiment, the proteins adhere to the surface of graphene and then the produced platelets may contain a graphene layer and a protein layer on the surface of the graphene layer. Electronic devices containing such platelets are also described.
