Fluorescent copper nanomaterials (CuNMs), including copper nanoparticles (CuNPs) and copper nanoclusters (CuNCs), become more and more popular with the abundant raw materials and low cost. A wide range of applications has been explored due to their fascinating properties such as low toxicity, remarkable water solubility, facile synthesis, large Stokes shifts, and good biocompatibility. As a kind of genetic material, DNA exhibits its molecular recognition function and diversity. The marriage between CuNMs and DNA endows DNA-templated CuNMs (DNA-CuNMs) with unique properties such as fluorescence, electrochemiluminescence and catalytic features. In this review, we summarize the synthesis and recent applications of DNA-CuNMs. Fluorescent CuNMs can be grown on various DNA scaffolds with special sequence design. T base plays an important role in the formation of CuNMs on DNA templates. These fluorescent DNA-CuNMs hold great prospect in logic gate construction, staining and biosensing of DNAs and RNAs, ions, proteins and enzymes, small molecules and so on.
荧光铜纳米材料（CuNMs），包括铜纳米粒子（CuNPs）和铜纳米团簇（CuNCs），由于其丰富的原料和低成本而变得越来越受欢迎。由于其具有低毒性、显著的水溶性、易于合成、大斯托克斯位移和良好的生物相容性等迷人特性，因此已经探索了广泛的应用。作为一种遗传物质，DNA 表现出其分子识别功能和多样性。CuNMs 与 DNA 的结合赋予了 DNA 模板铜纳米材料（DNA-CuNMs）独特的性质，如荧光、电化学发光和催化特性。在这篇综述中，我们总结了 DNA-CuNMs 的合成和最新应用。荧光 CuNMs 可以在具有特殊序列设计的各种 DNA 支架上生长。T 碱基在 DNA 模板上形成 CuNMs 中起着重要作用。这些荧光 DNA-CuNMs 在逻辑门构建、DNA 和 RNA、离子、蛋白质和酶、小分子等的染色和生物传感方面具有广阔的前景。
