Selective Assembly of Gold Nanowires on Patterned Gold Surfaces via Electrostatic Interactions
Gold nanowires, 50 nm in diameter and 1-2 μm in length, were prepared by template synthesis and modified by bifunctional thiols then suspended in different solvents. The dispersibility of nanowires is found to be strongly affected by the selection of solvents. The functionalized gold nanowires can be selectively assembled onto patterned surface via electrostatic interactions. It is possible that this simple process can be carried out in fabrication of more complicated structures, which are potentially useful in many applications such as nanoelectronic, photonic and SERS.
