摘　　要：贵金属纳米簇一般由几个到约一百个金属原子组成,具有超小粒径、生物相容性、低毒性以及独特的物理化学性质,近年来备受人们的关注,相比较于金纳米簇和银纳米簇,铜纳米簇的研究仍处于初始阶段。该文介绍了铜纳米簇的光学性质、合成方法和应用进展,重点总结了合成铜纳米簇的模板法、化学还原法、反相微乳液法、刻蚀法等,评述了铜纳米簇用于重金属离子、p H、小分子、生物分子等的荧光检测应用及其在生物标记、生物成像上的分析应用。Nobel metal nanoclusters （NCs） are composed of several to about one hundred atoms and have received considerable research interest due to their ultra small particle size, good biocompatibility, low toxicity, and unique physical and chemical properties. However, in comparison to the AuNCs and AgNCs, the research of copper nan- oclusters is still at the initial stage. In this review, we introduce the optical properties, synthesis methods and analyti- cal applications of copper nanoclusters, especially emphasis on summing up the CuNCs synthesis method like tem- plate synthesis method, chemical reduction method, inverse microemulsion method, etching method, etc. And the analytical applications for fluorescent detection of heavy metal ions, pH, small molecules and biological molecules as well as the applications in biological labeling and bioimaging have been reviewed.
