摘要
金属纳米团簇(NCs,尺寸通常小于2 nm)是一类新型的发光纳米材料,由于具有稳定性高、生物相容性好、毒性低等优点成为分析传感领域研究热点。Au/Ag双金属纳米团簇由于“银效应”使其比传统的AuNCs和AuNCs具有更高的量子产率和更强的稳定性,具有更广阔的应用前景。该文综述近年来Au/Ag双金属纳米团簇的表面功能化及其在分析传感方面的研究进展和分析原理,具体内容包括肽链、蛋白质、DNA对Au/Ag纳米团簇的表面功能化以及功能化的纳米团簇对金属离子、生物小分子和生物酶的分析检测应用。最后总结当前Au/Ag纳米团簇的合成及其在传感分析方面面临的挑战,并对今后的发展进行展望。希望能为Au/Ag纳米团簇在生物传感领域进一步发展提供参考。
Metal nanoclusters( NCs, usually smaller than 2 nm in size), as a new type of luminescent nanomaterials, have become a research hotspot in the field of analytical sensing due to Due to their high stability, good biocompatibility, and low toxicity. Au/Ag bimetallic nanoclusters have higher quantum yield and stronger stability than traditional AuNCs and AuNCs due to the “silver effect ”, and have a broader application prospect. In this paper, the surface functionalization of Au/Ag bimetallic nanoclusters in recent years and its research progress and analysis principle in analytical sensing are reviewed. This paper specifically introduced the functionalization of peptide chains, proteins, and DNA for nanoclusters, and its application in the analysis of metal ions, biological small molecules, and biological enzymes. Finally, the current synthesis of Au/Ag nanoclusters and their challenges in sensing detection are summarized, and an expectation for the future development has been made. It is hoped to provide reference for the further development of Au/Ag nanoclusters in the field of biosensing.
