Recent applications of electrogenerated chemiluminescence in chemical analysis

Analytical applications of electrogenerated chemiluminescence (ECL) are reviewed with emphasis on the years 1997-2000. Recent developments are described fur the ECL of organics, metal complexes and clusters. cathodic ECL on oxide covered electrodes. ECL based immunosensors, DNA-probe assays and enzymatic biosensors. Mechanisms are given for polyaromatic hydrocarbons, luminol/hydrogen peroxide, some cathodic ECL reactions and ruthenium complexes with and without co-reactants. New developments and improvements: of techniques and instrumentation and their application to analytes are described. The application of ECL for visualisation of electrochemical processes and imaging of surfaces is mentioned. (C) 2001 Elsevier Science B.V. All rights reserved.
