The scaffolding DNA sequence and the size of silver nanoclusters (AgNCs), confined in a DNA template are the key parameters in determining the fluorescent properties of DNA-stabilized silver nanoclusters (DNA/AgNCs). In addition, we suggest here that the structural shift of a DNA hairpin-dimer is as important as the DNA sequence in determining the emission wavelength of DNA/AgNCs. Furthermore, we show that the structural shift post AgNC formation can be triggered by incubation time and pre-AgNC formation under salt conditions. As an important factor in predicting the emission properties of DNA/AgNCs, the modulation of DNA secondary structures with either sequence changes or ionic conditions can be applied for the dual-color detection system of a target molecule. Particularly, the dual-color detection method may increase the reliability of DNA/AgNC sensors for miRNAs.

DNA模板在发夹和二聚体之间的结构转移可调节DNA模板的AgNC的发射颜色†
限制在DNA模板中的支架DNA序列和银纳米团簇（AgNCs）的大小是确定DNA稳定的银纳米团簇（DNA / AgNCs）荧光性质的关键参数。另外，我们在此建议，DNA发夹二聚体的结构转变与DNA序列在确定DNA / AgNC的发射波长方面同样重要。此外，我们表明，在盐条件下，孵育时间和前AgNC的形成可以触发AgNC形成后的结构转变。作为预测DNA / AgNCs发射特性的重要因素，具有序列变化或离子条件的DNA二级结构调节可应用于目标分子的双色检测系统。特别，
