Recent progress in developing enzyme and tissue‐based membrane electrodes

Abstract

The article summarizes the work of this laboratory on the design of eleven types of amperometricpenzyme electrodes mainly based on the CLARK oxygen sensor in connection with cross-linked oxidases. Special attention is paid to the sensors coupled with plant tissue slice for determining L-ascorbic acid and phenols. A “second generation” bienzyme electrode is reported which enables tow analytes forming a metabolic couple to be determined simultaneously. A principle of the first useful model of conductimetric enzyme electrode for assaying urea and arginase is also presented.
