Abstract

The present invention discloses a method for fixing terpyridyl ruthenium on the electrochemical electrode surface. Said method includes the following steps: mixing terpyridyl ruthenium and aqueous solution of noble metal nano particles protected by citric acid radical anions according to a certain ratio to obtain terpyridyl ruthenium-noble metal nano particles aggregate suspension, then fixing the aggregate suspension on the electrode surface which is hydroxylated.

Description

technical field [0001] The invention relates to a method for immobilizing ruthenium terpyridine on the surface of an electrochemical electrode Background technique [0002] 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 the fields of immunoassay, DNA analysis, chemical sensing and optical research, and it is also used in the fields of chromatography and capillary electrophoresis detection. [0003] Ru(bpy) 3 2+ It is one of the most widely used compounds with electrochemiluminescent properties. due to Ru(bpy) 3 2+ It has the reversibility of electrochemical and electrochemiluminescence, so its modification on the electrode surface has many advantages, such as saving reagents, improving the sensitivity of electrochemilu...
