Electrochemiluminescence reactions of metal complexes immobilized on surface of a magnetic microbead

摘要

In this study, electrochemiluminescence (ECL) reactions of Ru(bpy)_3~(2+) complex immobilized on magnetic microbeads (luminomicrobeads) were examined to develop highly sensitive ECL detection systems. It was found that intensity of ECL response of the luminomicrobeads was dependent on a coreactant (tripropylamine) concentration and solution pH. It is observed that the luminomicrobeads highly aggregated when collected on the electrode surface using a magnet, and the ECL intensity was strongly dependent on the degree of the aggregation of luminomicrobeads.
