Environmentally Friendly and Highly Sensitive Ruthenium(II) Tris(2,2′‐bipyridyl) Electrochemiluminescent System Using 2‐(Dibutylamino)ethanol as Co‐Reactant

Electric light orchestra: The electrochemiluminescence (ECL) intensity of the Ru(bpy)32+/2-(dibutylamino)ethanol (DBAE) system at Au and Pt electrodes are about 10 and 100 times, respectively, greater than that of the commonly used Ru(bpy)32+/tripropylamine (TPA) system (see picture). Thus, DBAE is a promising co-reactant for Ru(bpy)32+ ECL immunoassays and DNA probe assays.
