Abstract We report a fundamental study on the use of Ru(bpy) 3 2+ ‐based electrogenerated chemiluminescence (ECL) as an optical reporting system for detection redox‐active analytes closed bipolar microelectrodes, focused gaining in‐depth understanding correlation between ECL emission intensity and electrochemical current. demonstrate significant effect that size anodic cathodic poles has resulting signal show how this influences quantitative analyte electrode. By carefully designing geometry electrode, performance can be tuned to different concentration ranges. that, through simple voltammetric individual reactions, one understand coupled behavior accurately predict response range concentrations, enabling accurate prediction calibration curves.
