ResumoAbstract An enzyme electrode for hydrogen peroxide was developed with the aid of an easy and effective enzyme-immobilization. The enzyme electrode was made by holding an aggregate of a self-assembled amphiphilic block copolymer 1 and catalase on an oxygen electrode by use of microporous acetylcellulose membranes. The response of the electrode was linear between 4 × 10−6 – 4 × 10−4 M of hydrogen peroxide and remained unchanged after 50 days with over 150 measurements.
