Biogenic synthesis of AuPd nanocluster as a peroxidase mimic and its application for colorimetric assay of acid phosphatase

Based on the oxidation-redox mechanism of naturally occurring NADH along with its metal coordination properties, biogenic AuPd nanoclusters are directly synthesized with low concentration of metal precursors, showing outstanding peroxidase mimicking activities. Ultrasmall bimetallic nanozymes can rapidly form under the reduction and the stabilization of NADH, and their physicochemical properties are closely associated to the molar ratio of...
