Ag nanoclusters as nanozyme for detection of Hg2+ based on aggregation enhanced peroxidase-like activity

Key Points

• Hg2+ detection achieved through aggregation-induced increase in peroxidase-like activity of Ag nanoclusters, enhancing sensitivity.
• Key evidence shows a significant increase in detection sensitivity, with the method operating effectively in biochemical assays.
• Assessment using the aggregation-enhanced mechanism illustrates the performance of Ag nanoclusters in various test conditions.
• Highlights the potential application of Ag nanoclusters as nanozymes, emphasizing the need for real-world testing beyond the laboratory.
