Abstract

Monolayers of polymer-encapsulated Au nanoparticles with controlled density are obtained via a facile solution-based method by modulating the inter-particle repulsion and using empty polymer micelles as spacers. These Au nanoparticles are then used to catalyze the vapor transport growth of metal oxide nanowires, where distinct density-dependent growth regimes are identified.
