Enhanced electrochemiluminescence efficiency of Ru(II) derivative covalently linked carbon nanotubes hybrid.
The synthesized derivative Ru(bpy)(3) covalently linked CNTs hybrid shows good electrochemical activity and ca. 17 times higher luminescence quantum efficiency than the adsorbed derivative Ru(bpy)(3). The Ru-CNTs based ECL sensor exhibits high stability toward determination of TPA with a detection limit as low as 8.75 pM.
