DNA-templated silver and silver-based bimetallic clusters with remarkable and sequence-related catalytic activity toward 4-nitrophenol reduction

Herein, we report the excellent catalytic activity of DNA-AgNCs toward 4-nitrophenol reduction and a strategy for improving their catalytic performance by forming bimetallic clusters (Ag-Pd, Ag-Au and Ag-Pt). The analogous influence of sequences on the catalytic activity of these nanoclusters is disclosed, which is quite different from their erratic fluorescence properties.
