Peptide/Graphene Hybrid Assembly into Core/Shell Nanowires

Abstract

Hybrid assembly of peptides and graphene into core/shell nanowires is presented here. Electroconductive nanowires comprised of multilayered graphene shells wrapped around peptide nanowire cores were readily assembled upon diluting peptide solution into an aqueous reduced graphene dispersion. Calcination of peptide cores generated a hollow graphene-shell network with large surface area and high thermal/chemical stability.
