Özet

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.
