Au nanowires were produced at the interface of air/water by immersing a Au coated platinum tip into the growth solution containing CTAB, HAuCl4, and ascorbic acid. The Au coating layer is composed of 10−30 nm Au islands and these Au islands initiated the growth of Au crystals, which further produced Au nanowires via the template effect of the aligned cationic surfactant CTAB monolayer at the interface.
