Stabilization of aqueous suspensions of graphene single sheets by single‐stranded DNA is demonstrated using a range of physical methods. The negatively charged bio‐functionalized graphene sheets are spontaneously assembled into layered hybrid nanocomposites containing intercalated DNA molecules, or co‐intercalated mixtures of DNA and the redox protein, cytochrome c . Small‐molecule reducing agents readily access the intercalated proteins.
