DNA-templated fluorescent nanoclusters (NCs) have attracted increasing research interest on account of their prominent features, such as DNA sequence-dependent fluorescence, easy functionalization, wide availability, water solubility, and excellent biocompatibility. Coupling DNA templates with complementary DNA, aptamers, G-quadruplex, and so on has generated a large number of sensors. Additionally, the preparation and applications of DNA-templated fluorescent NCs in these sensing have been widely studied. This review firstly focuses on the properties of DNA-templated fluorescent NCs, and the synthesis of DNA-templated fluorescent NCs with different metals is then discussed. In the third part, we mainly introduce the applications of DNA-templated fluorescent NCs for sensing metal ions. At last, we further discuss the future perspectives of DNA-templated fluorescent NCs in the synthesis and sensing metal ions in the environmental and biological fields.
基于 DNA 的荧光纳米团簇（NCs）由于其独特的性质，如 DNA 序列依赖性荧光、易于功能化、广泛可用性、水溶性和出色的生物相容性，引起了越来越多的研究兴趣。将 DNA 模板与互补 DNA、适体、G-四链体等结合，产生了大量的传感器。此外，DNA 模板荧光 NCs 的制备及其在这些传感中的应用也得到了广泛的研究。本综述首先重点介绍了基于 DNA 的荧光 NCs 的性质，然后讨论了不同金属的 DNA 模板荧光 NCs 的合成。在第三部分，我们主要介绍了 DNA 模板荧光 NCs 在金属离子传感中的应用。最后，我们进一步讨论了 DNA 模板荧光 NCs 在环境和生物领域合成和传感金属离子的未来前景。
