英文摘要：

The noble metal clusters is a new class of fluorescent material. With a set of attractive features, such as ultrasmall size, fluorescence tenability and good biocompatibility, the clusters are ideal candidate for the fluorescent labels and detection. In this review, we summarize the synthesis and fluorescence characteristic of the clusters, and the recent development of their application in bioimging and in vitro detection.
