Imaging and Simulation of Ruthenium Derivative Coating Microbeads at the Opaque Electrode with Electrogenerated Chemiluminescence.

ABSTRACT: Electrogenerated chemiluminescence (ECL) imaging is gaining increasing attention in various fields because of its high sensitivity, low background, and good temporal and spatial resolution. However, ECL imaging of microsized objects at the opaque electrode via top-view configuration is challenged with the reactants' diffusion and light propagation. Here, we imaged and numerically simulated ruthenium derivative coating polystyrene microbeads (Ru1-PS@MB) at the glassy carbon electrode (GCE) via top-view configuration by ECL imaging. The ruthenium derivative (bis(2,2'-bipyridine)-4'-methyl-4-carboxybipyridine-ruthenium N-succinimidyl ester-bis (hexafluorophosphate), Ru1), a typical ECL reagent, was covalently linked onto the surface of aminated PS@MBs via the amide reaction.
