DNA mediated water-dispersible graphene fabrication and gold nanoparticle-graphene hybrid.
Water dispersible single- and bilayered graphene sheets are produced by a direct exfoliation from graphite flakes in the presence of pyrene-labeled single stranded DNAs, and the immobilized DNA on the graphene surface is further hybridized with a gold nanoparticle labeled complementary DNA to generate gold nanoparticle-graphene nanocomposites.
