Abstract: | The combination of immobilized enzymes and amperometry to build selective detection devices in flow-injection analysis and liquid chromatography is described. The pros and cons of enzyme electrodes and of immobilized enzyme reactors are discussed. The paper concentrates on the use of immobilized dehydrogenases, oxidases, peroxidases, and on electrodes on which these enzyme reactions can be selectively followed. The work in the field by the authors is reviewed. |
