Rapid synthesis of protein conjugated gold nanoclusters and their application in tea polyphenol sensing

- AuNCs-p-h were synthesized rapidly within 3 min at approximately 100 °C and contain remarkable peroxidase-like activity.
- A facile approach for TP sensing was developed based on the inhibition effect of TPs towards the peroxidase mimic activity of AuNCs-p-h.
- This novel sensing system can be readily used for TP quantification from real tea samples.
