One-step synthesis of UV-induced Pt nanotrees on the surface of DNA network

Yang LB, Sun B, Meng FL, Zhang MY, Chen X, Li MQ, Liu JH

Platinum metal nanotrees were prepared with assembling Pt nanciparticles onto DNA network template and reducing metal ions by photoinduced method. The concentration of DNA network and the reaction time play important roles in forming platinum nanotrees. The mechanism on the formation of the Pt nanotree is also discussed. (C) 2009 Elsevier Ltd.
