Chemically-wet treated silicon substrate was modified with self-assembled monolayer of 3-aminopropyl-trimethylsilane by aqueous phase silanization, giving an ultrasmooth and homogenous surface terminated with amino groups. Colloidal ld nanoparticles (15.7±2.0 nm)were adsorbed on such a surface with a submonolayer coverage and a random particle distribution. Increases in local surface coverage and packing order were induced by capping the assembled ld nanoparticles with alkanthiol molecules in an enthanolic solution.
