Abstract
A chemical system consisting of a metallic salt, a watersoluble polymeric matrix and an iron(III) citrate complex, acting as the photosensitive specie absorbing at two-photon, has been used to produce metal deposition upon exposure to a femtosecond laser. The fabrication of continuous and uniform gold nanowires has been optimized. Their dimensions vary from a few hundred nanometers to one micron for their widths, and range from a few to several hundred microns for their lengths.
