| Abstract |
Electrochemiluminescence (ECL) provides beneficial characteristics over photoluminescence, including low background emission, good temporal and spatial controllability, robustness, and instrumental simplicity. Thus, the ECL technique has been utilized as a versatile tool in a variety of analytical applications. To further expand the usefulness of ECL in analytical applications, many promising approaches have been suggested for amplification of ECL signals. Of the approaches, we recently reported the use of amine-terminated polyamidoamine (PAMAM) dendrimers for the enhancement of ECL. In the present talk, we discuss the recent reports about the use of dendrimers for enhanced ECL. First, we discuss highly enhanced ECL of Ru(bpy)32+ (bpy = 2,2’-bipyridyl) or luminol with appropriate coreactants on electrodes modified with amine-terminated dendrimers encapsulating catalytic nanoparticles [1-3]. Second, we discuss intense ECL of Ru(bpy)32+ in the presence of amine-terminated dendrimers as a coreactant [4].
