中文摘要	one-step synthesis of ru (bpy)(3) cl-2-immobilized (bpy = 2,2'-bipyridine) silica nanoparticles (ru-silica nanoparticles) for use in electrogenerated-chemiluminescence (ecl) detection is reported. ru-silica nanoparticles are prepared by using the stober method. compared with free ru(bpy)(3)cl-2, ru-silica nanoparticles are seen to exhibit a red-shift of the uv-vis absorbance peak and a longer fluorescence lifetime, which are attributed to the electrostatic interaction of ru(bpy)(3)(2+) and silica. because silica nanoparticles are used as immobilization matrices, the surfaces of ru-silica nanoparticles are easily modified or functionalized via the assembly of other nanoparticles, such as au. for ecl detection, au-colloid-modified ru-silica nanoparticles are immobilized on a 3-mercaptopropyl-trimethoxysilane-modified indium tin oxide electrode surface by au-s interaction; the surface concentration of electroactive ru(bpy)(3)cl-2 is obviously higher than that in silica films.
