Applications of tris(2,2′‐bipyridyl)ruthenium(II) in electrochemiluminescence

Abstract Electrochemiluminescence (ECL) of tris(2,2′‐bipyridyl)ruthenium(II) [Ru(bpy) 3 2+ ] has received considerable interest over broad applications due to its remarkably high sensitivity and extremely wide dynamic range. After a brief introduction of the ECL of Ru(bpy) 3 2+ , an overview of our recent research on enhanced ECL, fabrication of solid‐state ECL sensors, analytical application of an effective bioassay, and alignment of ECL with capillary electrophoresis (CE) and microchip CE is discussed in detail. Finally, we conclude with a look at the future challenges and prospects of the development of ECL. DOI 10.1002/tcr.201100017
