| 摘 要： | 利用静电吸附作用将联吡啶钌Ru(bpy)32+]负载到巯基化MCM-41介孔二氧化硅纳米颗粒上, 通过金-巯键修饰法将负载后的MCM-41固定在金电极表面, 发展了一种基于MCM-41负载联吡啶钌的电致化学发光传感器, 并研究了其电化学及电致化学发光行为. 基于三聚氰胺与增敏剂三正丙胺氨基结构的相似性, 将负载Ru(bpy)32+的MCM-41电致化学发光传感器用于三聚氰胺的检测, 获得了良好的检测效果, 为检测三聚氰胺提供了一种快速、简便的方法. 同时, 该研究为Ru(bpy)32+在电极表面的固定化提供了新思路.

| Abstract: | A novel electrogenerated chemiluminescence(ECL) sensor based on Ru(bpy)32+-doped MCM-41 mesoporous silica nanoparticles(MSN) was developed. The Ru(bpy)32+ was first loaded into the sulfhydryl modified MSN through the electrostatic absorption. Then the Ru(bpy)32+-doped MSN was immobilized onto the surface of Au electrode by Au-S interaction. The properties of electrochemistry and electrogenerated chemiluminescence(ECL) were also investigated. The amino 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)32+ onto the electrode surface. |
