Recent advances in the bioanalytical and biomedical applications of DNA-templated silver nanoclusters
2020
Abstract Silver nanoclusters stabilized with DNA scaffolds, with excellent physical and chemical properties, have emerged as a versatile tool in biomedical systems. Silver nanoclusters as a late-model nanomaterial with a small size less than 2 nm shows good stability and strong fluorescence. By using DNA with diverse sequence and structures, soluble DNA-templated silver nanoclusters are facilely prepared. They possess tunable fluorescence emission and are suitable with multifunctional designs. Extensive efforts have been put into the application potential of this biocompatible material for biosensing, bioimaging and therapy. Here we are committed to outline the recent advances of DNA-templated silver nanoclusters in biomedical application. The future prospect and challenges are then discussed considering rising progress. Though there is still a long way for illuminating the mechanism behind traits and conducting further clinical trials, we believe DNA-templated silver nanoclusters’ unprecedented unique properties will finally benefit medical progress.
