Controlling the composition of plasmonic nanoparticle arrays via galvanic displacement reactions on block copolymer nanotemplates

Abstract

A versatile and facile route to control the composition of plasmonic nanoparticles (NP) aligned in a configuration of two dimensional nano-arrays is presented by applying galvanic displacement reactions on a pre-defined noble metal NP arrays which were prepared from diblock copolymer inverse micelles containing metal precursors. © 2011 The Royal Society of Chemistry.
