Abstract:
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.
