Ccrystal structure of DNA-stabilized silver nanocluster

Nanoclusters are little 'heaps' of a few atoms that often have interesting optical properties and could become useful probes for imaging processes in areas such as biomedicine and diagnostics. Researchers have introduced a nanocluster of 16 silver atoms stabilized by a wrapping of DNA strands. Using X-ray analysis, they were able to determine the crystal structure and identify important interactions within it.
