贵金属(Au, Ag, Pt等)纳米簇通常指的是由几个到约一百个原子组成的分子聚集体, 具有生物相容性好、超小尺寸(<2 nm)以及优异的物理化学性质, 尤其是能发出较强荧光等特点引起了人们的广泛关注. 目前多种贵金属纳米簇的合成方法已相继被报道, 且已应用于生物荧光成像、电化学发光、生物传感器以及细胞标记等多个领域. 本文共分为五部分, 首先重点介绍近几年兴起的以蛋白和多肽为模板来合成纳米簇的方法及优点, 并随后总结列举了文献中所采用的蛋白以及自主设计的多肽组分序列的类别, 随后探索了蛋白和多肽中的特定氨基酸与合成的贵金属纳米簇的荧光波长、量子产率、粒径之间的联系. 本文最后总结阐述了蛋白和多肽为模板成功合成贵金属纳米簇的先决条件并对其生物医学应用前景进行了展望.

Noble metal nanoclusters (NMNCs) are the molecular aggregates, which are composed of several to one hundred atoms, and possess good biocompatibility, ultra small size (smaller than 2 nm), excellent physical and chemical properties, especially the strong photoluminescence, have aroused people's wide concern. Currently various kinds of methods to synthesize the NMNCs have been reported, and the NMNCs have been applied in many fields, such as bioimaging, electrochemiluminesence (ECL), biosensor and cell labeling. After BSA was the first protein to synthesize the Au nanoclusters, subsequently other kinds of similar protein and self-designed peptide appear. This review focuses on the advantages of this emerging method in recent years that choosing the protein and peptide as the template, simultaneously lists the protein and the peptide sequence reported in recent years, and explores the connection between the specific amino acids composition of protein or peptide and the wavelength, quantum yield (QY), size of NMNCs. In the end, we explain the prerequisits possessed of protein and peptide in synthesizing the NMNCs as well as predict the further development and the future of this synthesis method based on the protein and peptide as the template in the biomedical application.
