Insights into the crystal packing interactions of a 960-nm-emissive DNA-stabilized silver nanocluster.
Chem.Commun.(Camb.), 2026

PubMed Abstract: DNA-stabilized silver nanoclusters (DNA-AgNCs) can be finely tuned through DNA sequence design. Here, we present mutations in a DNA strand that stabilize an [AgCl] cluster, which remains largely unaltered, as confirmed by spectroscopy and mass spectrometry. The crystal structure of one mutant further reveals previously unseen packing interactions among DNA-AgNCs.
