Application of UV-curable diazoresin. II. Characteristics of the immobilized glucose oxidase membrane†

The characteristics of the enzyme electrode, developed using the immobilized glucose oxidase membranes, were investigated. The enzyme membranes were prepared from poly(vinyl alcohol)-diazoresin and poly(vinyl alcohol)-sensitizer systems, cross-linked by means of ultraviolet light irradiation. Temperature and pH dependencies of the relative activity, stability in repeating usage, storage stability, and calibration plots were evaluated. The unstable phenomenon, found in the initial usage of the immobilized glucose oxidas membrane, which was prepared from poly(vinyl alcohol)-sensitizer system, was also investigated.
