Green synthesis of peptide-templated gold nanoclusters as novel fluorescence probes for detecting protein kinase activity.

A green method was employed for synthesizing peptide-templated nanoclusters without requiring strong reducing agents. Using synthetic peptide–gold nanoclusters as fluorescence probes, a novel assay for detecting protein kinase is developed based on phosphorylation against carboxypeptidase Y digestion.
