Utilizing intrinsic surface properties to direct and control nanostructure growth on a large-scale surface is fundamentally interesting and holds great technological promise.  We have developed a novel �bottom-up� approach to fabricating sub-10 nm Au nanoparticles on a nanostructured Ag surface via a chemical solution deposition by using localized surface plasmon resonance (SPR) excitation.  The Au nanoparticle sizes are tunable from 3 to 10 nm by easily adjusting the deposition time.  Unlike the nanoparticles synthesized through wet chemistry methods, these Au nanoparticles are thermally stable and their surfaces are free of organic ligand protection.  Moreover, the fabricated Au nanoparticles show high efficiency for CO oxidation in the presence of visible light.
