Gold nanoelectrodes were fabricated by ap- proach of combining surface self-assembly with nanolitho- graphy electrochemically through a conductive AFM tip. The controllable structure with width and distance in nanometer as a template was constructed by nanolithography patterning process, which was accomplished by a conductive AFM tip on certain highly ordered long-tail organosilane monolayers. Then through adsorption of Cd2+ and exposure of the Cd2+-loaded surface to gaseous H2S, CdS nanowires were generated in a template-controlled self-assembly process. Finally, metallic gold nanowires were conversed from CdS nanowires by treatment with the aqueous solution of HAuCl4 via a redox chemical process, which had good conductivity proved by C-AFM.
