Metallic nanoclusters: From synthetic challenges to applications of their unique properties in food contamination detection
Frequent food safety problems have brought great threat to people’s life and health in recent years. Therefore, it is of urgent demand to exploit efficient sensing methods for detecting contaminants in food matrix. Effective food safety monitoring technology can be developed by integrating food detection with functional nanomaterials. Nowadays, metal nanoclusters (MNCs) are regarded as very promising nanomaterials on account of their significantly superior properties over metal nanoparticles. The excellent optical property, electrical performance and catalytic ability broaden the application prospect of MNCs for developing new sensors. This review comprehensively introduces the main synthesis strategies of MNCs, and summarizes the applications of them to construct sensitive and specific sensing strategies for analyzing various contaminants in food substrates in the past ten years. Furthermore, the potential applications of fluorescence, electrochemistry (including electrochemical catalysis and electrochemiluminescence), and mimic enzyme properties of MNCs in food safety monitoring were discussed in detail, and their sensing mechanisms were elaborately clarified through typical sensing application examples. The review is concluded with the perspective on the application challenges and development tendency of MNCs-based sensors. We hope valuable ideas will be provided in this review for designing MNCs-based sensors according to their unique properties in sensing fields.
