摘要

Surface modifications with organic molecules comprise a versatile tool to enable applications of graphene in the field of biotechnology. In this context, interfacing graphene with ligands such as antibodies and aptamers constitutes a prevalent methodology for the realization of bioselective graphene surfaces. Following this concept, in this work, we describe two novel routes for surface modificati...
