In this experimental study fluorescent silver clusters on a tRNA matrix were synthesized for the first time. Two types of fluorescent complexes emitting in the green (550 nm) and red (635 nm) regions of the visible spectrum were obtained. Using FTIR spectroscopy, we identified possible binding sites for the clusters, which appeared to be within the helical regions of tRNA. It was also shown that tRNA retained its double helical structure after the cluster formation, which is essential for its functionality.
在本实验研究中，首次在转运核糖核酸（tRNA）基质上合成了荧光银簇。获得了两种在可见光谱的绿色（550纳米）和红色（635纳米）区域发射荧光的复合物。利用傅里叶变换红外光谱（FTIR），我们确定了这些簇可能的结合位点，这些位点似乎位于tRNA的螺旋区域内。研究还表明，在形成簇之后，tRNA保留了其双螺旋结构，这对其功能至关重要。
