This article begins with the introduction, presenting the research background and development history of chiral metal nanoclusters, and elaborating on their extensive application prospects in asymmetric catalysis, biomedicine, optical materials, etc. In the section on the exploration of chiral sources, the three sources of chirality—chiral metal cores, asymmetric arrangement of surface ligands on nanoclusters, and chiral ligands—are analyzed in detail, supported by specific cases and research results. Subsequently, the article delves into the resolution techniques of chiral metal nanoclusters, including supramolecular assembly strategies, crystalline self-assembly, chiral ion pair strategies, efficient chiral liquid chromatography, chiral ligand resolution, and chiral inducer resolution, each with corresponding research examples and achievements. In the application section, it focuses on the applications of chiral metal nanoclusters in asymmetric catalysis and the construction of optical devices, demonstrating their potential through specific research results. Finally, in the summary and outlook section, the current research achievements are summarized, and the future research directions and challenges are pointed out, such as improving optical activity, achieving large-scale production, and expanding application fields.
