基于MCM-41负载联吡啶钌的电致化学发光传感器
Electrogenerated Chemiluminescence Biosensor Based on Ru(bpy) 2+3 Doped Mesoporous Silica Nanoparticles
摘要
Abstract
A novel electrogenerated chemiluminescence(ECL) sensor based on Ru( bpy)2+3-doped MCM-41 mesoporous silica nanoparticles ( MSN) was developed. The Ru ( bpy)2+3 was first loaded into the sulfhydryl modified MSN through the electrostatic absorption. Then the Ru(bpy)2+3-doped MSN was immobilized onto the surface of Au electrode by Au-S interaction. The properties of electrochemistry and electrogenerated chemilu-minescence(ECL) were also investigated. The ami no structure of melamine is similar to tripropylamine, so we attempted to branch out the application of MCM-41 into the detection of melamine, the ECL sensor provided a new assay for the detection of melamine. Furthermore, the research provided a new approach for the immobilization of Ru(bpy)2+3 onto the electrode surface.关键词
