Synthesis of nmicro-size and nanometer particles containing trigeminy ruthenium pyridine

Abstract

Synthesis of micron and nanometer particle containing Ru(bpy)32+ is carried out by mixing Ru(bpy)32+ with anionic compound or anionic polyelectrolyte solution proportionally and preparing mass micron and nanometer particle containing Ru(bpy)32+. It has excellent electrochemiluminescent performance and is simple and fast. It can be used for capillary electrophoresis or solid ECL inspection.

Description

technical field [0001] The invention relates to a new method for synthesizing micron and nanometer particles containing ruthenium terpyridine. Background technique [0002] Electrochemiluminescence (also known as electrochemiluminescence, ECL) refers to the generation of some special substances on the electrode surface by electrochemical methods, and these substances form excited states through electron transfer between them or with other components in the system. The phenomenon of luminescence produced by returning the excited state to the ground state. In recent years, electrochemiluminescence has attracted widespread attention due to its good controllability, high sensitivity, good selectivity, simple instrumentation, and fast analysis speed, and has developed into an important and valuable analytical and detection method, widely used It is used in immunoassays and DNA analysis, chemical sensing, imaging, laser and optical research, and is also used in chromatography and...
