We report a new strategy for the fabrication of Ag–Au bimetallic nanowire (NW) arrays by taking advantage of interfacial assembly of plasmonic nanoparticles and galvanic replacement reactions. Galvanic replacement reactions led to the formation of nanospikes on NWs, giving rise to a high density of...
