摘　　要：金纳米簇(gold nanoclusters, Au NCs)是粒径小于2 nm (不含配体外壳)或组成金原子数小于150的金原子聚集体。由于其具有特异的小尺寸效应、荧光性质和催化活性而被广泛研究。本文总结了采用不同生物分子和化学合成分子作为配体,制备具有精确原子数的金纳米簇的方法;讨论了在制备过程中不同因素对制备产物的影响;介绍了含有精确原子数的金纳米簇在分析物检测、催化、生物成像和药物递送中的相关应用,为金纳米簇的制备技术和生物医学的研究和应用提供参考。Gold nanoclusters（AuNCs） are gold atom aggregates less than 2 nm（excluding the ligand shell） or 150 atoms. It has been widely studied due to its small size effect, fluorescence property, and catalytic activity. In this review, research progress in the preparation of gold nanoclusters containing accurate atom numbers using biomolecules and chemically synthesized molecules as ligands have been summarized. The factors that affect the preparation of gold nanoclusters have been discussed. The applications of Au NCs having accurate atomic numbers in the fields of analyte assay, catalysis, bioimaging, and drug delivery have been introduced. This review provides references to the further researches on the preparation technology and biomedical applications of AuNCs.
