Colloidal gold nanoparticles(12.0±1.0 nm) were adsorbed on such an amino-terminated surface with a submonolayer coverage. Randomly distributed gold nanoparticles were reorganized into two-dimensional close-packed aggregates when treated with alkanthiol molecules.Large size two dimensional domains or ring like structures of gold nanoparticles can be induced by solvent flow and evaporation.展开更多
