Nanoclusters: Evidence for Rod-Shaped DNA-Stabilized Silver Nanocluster Emitters (Adv. Mater. 20/2013)
Fluorescent, DNA-stabilized silver clusters are generating growing interest as selective sensors and biolabels, but the origins for their wideranging, sequence-tuned colors are obscure. On page 2797, Elisabeth Gwinn and co-workers report that compositionally pure complexes with 10–24 silver atoms, formed on a variety of DNA strands, all contain both neutral and cationic silver. Optical properties indicate a nanorod geometry, with color reflecting the length of a silver atom chain in the nanorod core.
