Upon growth of a thin metal (Pd, Pt, or Au) layer, the NW winds around itself to give a metallic double helix. We propose that the winding originates from the chirality within the as-synthesized Au-Ag NWs, which were induced to untwist upon metal deposition. © 2011 American Chemical Society.||Source Title:||Journal of the American Chemical Society||URI:||http://scholarbank.nus.edu.sg/handle/10635/63592||ISSN:||00027863||DOI:||10.1021/ja208121c|
