| New Materials for Electrochemiluminescent Analysis Guobao Xu1; 1STATE KEY LABORATORY OF ELECTROANALYTICAL CHEMISTRY, CHANGCHUN INSTITUTE OF APPLIED CHEMISTRY, CHINESE ACADEMY OF SCIENCES, Changchun, China; PAPER: 252/Electrochemistry/Regular (Oral) SCHEDULED: 14:25/Tue./Copacabana B (150/1st) ABSTRACT: Electrochemiluminescence (ECL), or electrogenerated chemiluminescence, is an electrochemically triggered light-emitting phenomenon. It has been extensively studied in immunoassays, DNA probe assays, aptasensors, enzymatic biosensors, coreactant detection, light-emitting devices, drug screening, and so on. It is one of the most successful electrochemical in vitro diagnostic techniques. Luminophores, coreactants, electrodes, electrocatalysts, quenchers, and microbeads are often used in ECL. These materials have critical effects on ECL performance. Herein, we reported some new materials with excellent features, such as luminophor ([Ru(bpy)<sub>2</sub>dppz]<sup>2+</sup>), coreactant (2-(dibutylamino)ethanol), electrodes (stainless steel electrode and bismuth electrode), noble metal nanocrystal electrocatalyst with high-index facets, single-walled carbon nanohorn ECL quencher, and microbead [1-5].
