Absaract：

A  novel method for producing complex metallic nanostructures of programmable  design is presented. DNA origami  templates, modified  to   have  DNA binding sites  with a  uniquely coded  sequence,   were adsorbed onto silicon dioxide substrates.Gold nanoparticles     functionalized     with      the cDNA sequence were then attached. These seed nanoparticles were later  enlarged, and even fused, by electroless deposition of silver. Using this  method, a variety of metallic structures, including rings, pairs of bars, and H  shapes, was constructed. Preliminary results on plasmonic applications of the  metallic nanostructures are presented as well.
