荧光DNA稳定的银纳米团簇含有阳离子和中性银原子。组成上纯的溶液的吸收光谱遵循预期的棒状银簇的趋势，与从单个纳米簇测量的偏振发射一致。这些数据表明，一个棒状组装的银原子，与银阳离子介导的连接到基地。
Fluorescent DNA-stabilized silver nanoclusters contain both cationic and neutral silver atoms. The absorbance spectra of compositionally pure solutions follow the trend expected for rod-shaped silver clusters, consistent with the polarized emission measured from individual nanoclusters. The data suggest a rod-like assembly of silver atoms, with silver cations mediating attachment to the bases.
