This paper reported that the peroxidase-like activity of DNA-Ag/Pt nanoclusters (NCs) can be inhibited significantly by l-cysteine. Based on this finding, a highly sensitive and selective colorimetric detection for l-cysteine was developed with a detection limit (LOD) of 2.0nM and a linear range fro...
