Palladium wire-shaped nanoparticles from single synthetic polycation molecules

Here we described simple chemical route to fabricate wire-shaped metallic nanoparticles of about 5 nm in a diameter and of 1000 nm in a length from single synthetic polycations. The preparation is based on the deposition of Pd-clusters on single poly(methacryloyloxyethyl dimethylbenzylammonium chloride) molecules adsorbed on Si-wafers from aqueous solution. The length and the diameter of nanowires are determined by the length and the diameter of the underlying polymer chains.
