Thiolated DNA-templated silver nanoclusters with strong fluorescence emission and a long shelf-life

Abstract

Thiolated DNA (DNA-SH) was employed as a template in the synthesis and stabilization of AgNCs (DNA-SH-AgNCs). Resulting from the synergistic protective effect of specific Ag⁺-DNA interactions and Ag-S bonding, DNA-SH-AgNCs exhibited high quantum yields and resistance to oxidation.
