Abstract

A simple, large scale, and one-step process for the preparation of tris(2,2′-bipyridyl)ruthenium(I) (Ru(bpy)32+) doped SiO2@carbon nanotubes (MWNTs) coaxial nanocable used for an ultrasensitive electrochemiluminescence (ECL) is presented for the first time. More importantly, a directly coated as-formed functional material on ITO electrode surface exhibits excellent ECL behavior, good stability, and high sensitivity in the presence of tripropylamine (TPA). This novel functional material will find potential applications in biosensor, electrophoresis and electroanalysis.
