Abstract
The electrochemistry and electrochemiluminescence (ECL) of novel three-dimensional nanostructured Ru(bpy)32+/Ni(OH)2 microspheres were investigated for the first time. The negatively charged porous Ni(OH)2 microspheres composed of Ni(OH)2 nanowires were specifically designed to interact with Ru(bpy)32+. The large surface area and porous structure of Ni(OH)2 microspheres enhance loading of Ru(bpy)32+ and mass transport of the model analyte, tripropylamine (TPA). Excellent ECL performance of the presented sensor was achieved including good stability and wide linear range from 7.7Â ÃÂ 10â10 to 3.8Â ÃÂ 10â3Â M with the detection limit of 2.6Â ÃÂ 10â10Â M to TPA.
