DNA‐Guided Metal‐Nanoparticle Formation on Graphene Oxide Surface

A simple and universal route for the preparation of metal–graphene oxide (GO) heterostructures with controllable nanoparticle size and shape using double-stranded DNA (dsDNA) as a template is reported. This proof-of-concept work successfully demonstrates that dsDNA can be adsorbed onto GO to create biocompatible and easily functionalizable Ag–GO, Au–GO, Cu–GO, Pt–GO, and Au/Cu/Pt–GO heterostructures using the same experimental conditions for each of the multicomposite nanoparticles.
