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)3]2+/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)3]2+/tripropylamine (TPA) system (see picture). Thus, DBAE is a promising co-reactant for [Ru(bpy)3]2+ ECL immunoassays and DNA probe assays.
