DNA作为一个多功能的模板，用于少原子银簇及其有组织的自组装。这些簇具有独特的结构和生物物理特性，被编程到DNA模板序列中，从而产生丰富的荧光团调色板，有望成为化学和生物分子传感器，生物标记和纳米光子元件。本文综述了DNA模板银团簇（AgN-DNAs）的基本研究进展，包括AgN-DNAs合成前体--银介导的DNA复合物的作用、AgN-DNAs的结构与性质的关系以及激发态动力学导致的荧光。我们还总结了DNA序列如何选择AgN-DNA的属性，以及如何利用序列进行知情设计和有序多簇组装的当前理解。为了促进未来的研究，我们结束了几个机会和挑战的讨论，基本和应用，为AgN-DNA研究界。对这类金属簇荧光团的全面基本理解可以为合理设计和推进其在基于荧光的传感，生物科学，纳米光子学和催化中的应用提供基础。DNA可以稳定银团簇与序列调谐荧光。我们回顾了DNA模板银团簇的结构和性质的最新进展，它们的合理设计和有序排列，以及新出现的挑战。
DNA serves as a versatile template for few-atom silver clusters and their organized self-assembly. These clusters possess unique structural and photophysical properties that are programmed into the DNA template sequence, resulting in a rich palette of fluorophores which hold promise as chemical and biomolecular sensors, biolabels, and nanophotonic elements. Here, we review recent advances in the fundamental understanding of DNA-templated silver clusters (AgN-DNAs), including the role played by the silver-mediated DNA complexes which are synthetic precursors to AgN-DNAs, structure–property relations of AgN-DNAs, and the excited state dynamics leading to fluorescence in these clusters. We also summarize the current understanding of how DNA sequence selects the properties of AgN-DNAs and how sequence can be harnessed for informed design and for ordered multi-cluster assembly. To catalyze future research, we end with a discussion of several opportunities and challenges, both fundamental and applied, for the AgN-DNA research community. A comprehensive fundamental understanding of this class of metal cluster fluorophores can provide the basis for rational design and for advancement of their applications in fluorescence-based sensing, biosciences, nanophotonics, and catalysis. DNA can stabilize silver clusters with sequence-tuned fluorescence. We review recent advances in understanding of the structures and properties of DNA-templated silver clusters, their rational design and ordered arrangement, and emerging challenges.
