In electrogenerated chemiluminescence (ECL), electrode materials affect the mechanism of signal generation, and therefore the emission intensity. This is particularly important in ECL imaging, where not only the total light emission, but its local state is crucial for visualizing the emission layer and exhibit an accurate and precise ECL image. The careful selection of electrode material is pivotal in ECL imaging because it has to be paired with the ECL system under investigation for the best results. This chapter reports an accurate selection of the most important electrode materials and their impact on ECL generation, with a special focus on the tris(2,2′-bipyridine)ruthenium(II)/tri-n-propylamine ECL system owing its extensive use in research and commercial clinical analyzers.

摘要

In electrogenerated chemiluminescence (ECL), electrode materials affect the mechanism of signal generation, and therefore the emission intensity. This is particularly important in ECL imaging, where not only the total light emission, but its local state is crucial for visualizing the emission layer and exhibit an accurate and precise ECL image. The careful selection of electrode material is pivotal in ECL imaging because it has to be paired with the ECL system under investigation for the best results. This chapter reports an accurate selection of the most important electrode materials and their impact on ECL generation, with a special focus on the tris(2,2′-bipyridine)ruthenium(II)/tri-n-propylamine ECL system owing its extensive use in research and commercial clinical analyzers.
