We report the discovery of a DNA sequence that templates a highly stable fluorescent silver nanocluster. In contrast to other DNA templated silver nanoclusters that have a relatively short shelf-life, the fluorescent species templated in this new DNA sequence retains significant fluorescence for at least a year. Moreover, this new silver nanocluster possesses low cellular toxicity and enhanced thermal, oxidative, and chemical stability.
我们报告了一种 DNA 序列的发现，该序列可以模板化出高度稳定的荧光银纳米簇。与其他具有相对较短保质期的 DNA 模板化银纳米簇相比，这种新 DNA 序列模板化的荧光物质至少可以保持一年的显著荧光。此外，这种新的银纳米簇具有低细胞毒性和增强的热、氧化和化学稳定性。
