Protein–DNA interactions: a novel approach to improve the fluorescence stability of DNA/Ag nanoclusters†
Abstract
Protein–DNA interactions are known to play an important role in a variety of biological processes. We have shown here that protein–DNA binding events can also be used to greatly improve the fluorescence stability of DNA-templated Ag nanoclusters (Ag NCs), which would be highly beneficial for Ag NCs in applications of biosensing/imaging.
