| Popis: | 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 spheres (PS), were used as working electrodes for the electrochemical deposition of AuNPs. After removing the PS, a large-scale, well-ordered honeycomb structure of AuNPs remains. In each cell of the honeycomb network, there is a size gradient of AuNPs with radii varying from 5 nm to 30 nm.
