Nanoscale platinum wires have been prepared by means of an electrochemical technique on DNA template.The platinum nanowires were characterized via transmission electron microscopy（TEM） and X-ray diffraction（XRD）.The length of the nanowires was about 50 nm and the diameter was about 1.3 μm.It was found that the concentration of PtCl4,activation time,electrolytic potential and reducing time affected the sizes and shapes of the platinum nanowires.
