Construction of silver nanowires on DNA template by an electrochemical technique

Silver metal nanowires were prepared with assembling Ag ions onto DNA template and reducing metal ions by a kind of electrochemical method. Silver metal nanowires were characterized by transmission electron microscopy (TEM) and X-ray diffraction (XRD). The diameter of the nanowires is about 50 nm and the length of the nanowires is about 6.0 μm. The affection of experimental conditions on the formation of the silver nanowires was examined.
