A wet-chemistry strategy for fabricating multilayers of gold nanoparticles on solid substrates is proposed. The strategy is based on immobilization of discrete gold colloid arrays on aminosilane-functionalized substrate with subsequent immersion of the substrate in gold colloidal and p-aminothiophen...
