我们报告的DNA序列的模板高度稳定的荧光银纳米簇的发现。与具有相对短的保质期的其他DNA模板化的银纳米团簇相比，在该新DNA序列中模板化的荧光物质保留显著的荧光至少一年。此外，这种新的银纳米团簇具有低细胞毒性和增强的热、氧化和化学稳定性。
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.
