Stable silver nanoparticle-DNA conjugates for directed self-assembly of core-satellite silver-gold nanoclusters.
We report a novel strategy to functionalize silver nanoparticles with chimeric phosphorothioate modified DNA (ps-po-DNA) and the fabrication of bimetallic core-satellite nanoclusters that each contain a silver core (diameter 32 nm) surrounded by 5 nm gold NPs.
