Multiscale organization of a size gradient of gold nanoparticles in a honeycomb structure network

Multiscale organization of a size gradient of gold nanoparticles in a honeycomb structure network

A fast and cost-effective technique for the formation of a size gradient of gold nanoparticles (AuNPs) in a honeycomb network is described. It combines nanosphere lithography (NSL) and electrochemical deposition. Indium tin oxide (ITO) substrates modified with a close-packed monolayer of polystyrene...
