Simply peel off the layers: Functionalities from nature may be used to meet the demands of contemporary materials science in terms of the efficient and safe production of high-quality, versatile materials. Thus, the spontaneous absorption on graphite of small amphiphilic proteins known as hydrophobins from an aqueous phase, followed by sonication, led to the exfoliation and stabilization of graphene sheets (see picture).
