Techniques mesh to form a wire array: Methods for the electrodeposition of metal nanowire arrays are described. Metal nanowires are obtained when the electrodeposition of either a metal oxide or a metal occurs selectively at the step-edge defects present on a HOPG electrode. The resulting wires are formed in parallel arrays of 100–1000 wires, reflecting the organization of step edges on the HOPG surface. These nanowire arrays may be lifted off the HOPG surface by embedding them in a cyanoacrylate film, which thereby facilitates the incorporation of metal nanowire arrays into devices such as the hydrogen gas sensor shown.
