Advance in high-efficient fluorescent metal nanoclusters for the detection of heavy metal ions
Heavy metal ions with the characteristics of environmental persistence,bioaccumulation and biotoxicity,pose a severe threat to human life and safety.Therefore,it is of great significance to develop highly sensitive,selective,rapid and convenient methods for the detection of heavy metal ions.Luminescent metal nanoclusters(metal nanoclusters,MNCs)have received extensive attention for the detection of heavy metal ions due to their biocompatibility,small size for easy labeling,high photostability and low toxicity.The sensitivity of metal nanocluster-based sensing is closely related to the fluorescence properties of MNCs,thus a deep understanding of the enhancement mechanism of metal nanocluster fluorescence is the cornerstone for improving the performance of metal nanoclusters-based heavy metal ions sensing.Based on this,this paper summarizes the fluorescence enhanced mechanism for the metal nanoclusters and introduces the application of metal nanoclusters for the detection of heavy metal ions and their future development,which provides a reference for the development and application of high-efficient metal nanoclusters.
