Dynamically imaging collision electrochemistry of single electrochemiluminescence nano-emitters

Abstract

Dynamically imaging stochastic collision electrochemistry of single nanoparticles by electrochemiluminescence microscopy enables visualization of diverse collision behaviours.

Spatially resolved electrochemiluminescence through a chemical lens

“…12,13,[18][19][20][21][22] Furthermore, the surface-conned emission allows ECLM to quantify different analytes simultaneously [23][24][25][26] as well as permitting high resolution visualization of nanomaterials such as nanoparticles and nanorods. [27][28][29][30][31] In ECL, the emission layer is typically conned in the near proximity of the electrode surface 32 and it is limited by the lifetime of the coreactant radicals (vide infra) and cannot be easily controlled. 33 Different strategies have been proposed to extend the ECL emitting layer including the application of the so-called Faraday cage 34 and the choice of different coreactants.…”

“…1). In particular, the TPrA radical cation, with its limited lifetime [half-life (t 1/2 ), ∼200 µs], is not expected to diffuse farther than 3 µm from the electrode surface [29][30][31][32] .…”
