Abstract

Plated gold: Self-assembly of core/shell nanostructures occurs spontaneously when gold nanoparticles are combined with amphiphilic block copolymers. Polymer cross-linking then topologically fixes the composite nanostructure (see picture). The thickness of the polymer shell, as well as the optical and chemical properties of the composite nanostructure, are precisely determined by the molecular characteristics of the assembled block copolymer.
