Abstract

A strategy for rapid synthesis of a chemopalette of fluorescent Ag nanoclusters based on efficient directors by only incorporating mutated bases of a C-rich ssDNA as template was proposed and used as a new fluorescence turn-on highly selective and sensitive detection method for cysteine without the interference of GSH and Hcy.
