Plasmon-Enhanced Electrochemiluminescence at the Single-Nanoparticle Level.Plasmon-enhanced electrochemiluminescence (ECL) at the single-nanoparticle (NP) level was investigated by ECL microscopy.  This plasmon enhanced ECL microscopy for arrayed single NPs provides a reliable tool for screening electrocatalytic activity at a single particle.

Finite Difference Time Domain (FDTD) simulations conformed well with the experimental results.
