We used near-field interactions with a silver nanorod (AgNR) to greatly enhance luminescence of a lanthanide (Ln) chelate. The enhancement factor was 280-fold, making single lanthanide luminescence detectable. This is also the first observation on single molecule detection (SMD) of a lanthanide dye.
我们利用银纳米棒(AgNR)的近场相互作用极大地增强了镧系螯合物的发光。增强因子为280倍,使得单个镧系元素发光可被检测到。这也是首次对镧系染料进行单分子检测(SMD)的观察。
