Abstract

Based on the property that cyclodextrin substances can form supramolecular inclusion

we studied the ability of electroneutral -cyclodextrin (-CD) or electronegative carboxymethyl--cyclodextrin (CM--CD) for forming supramolecular inclusion with electrochemiluminescence (ECL) active substance Ru(bpy)

and their ECL enhancement. The results show that the supramolecular inclusions can enhance the ECL of Ru(bpy)

. Compared with Ru(bpy)

CM--CD increases 1.42 times while only 1.28 times for -CD. Using SiO

nanoparticles with negative surface charge as carriers

their absorption capacity for Ru(bpy)

supramolecular inclusion was investigated. The results show that SiO

nanoparticle carriers have a stronger adsorption capacity for -CD supramolecular inclusion of Ru(bpy)

. SiO

composite nanoparticles of -CD-Ru(bpy)

supramolecular inclusion with srtongest ECL signal amplification were prepared in this paper.
