PURPOSE:To carry out the partial inactivation of an immobilized enzyme membrane, in high efficiency, and to prepare a partially inactivated immobilized enzyme membrane, easily, by irradiating a specific part of the immobilized enzyme membrane with electromagnetic wave to inactivate the enzyme of that part. CONSTITUTION:A specific part of an immobilized enzyme membrane is irradiated with electromagnetic wave such as ultraviolet radiation, X-ray, infrared radiation, microwave, etc. to inactivate the enzyme of the part and to obtain a partially inactivated immobilized enzyme membrane. For example, a differential enzyme electrode can be produced with extremely simple process, by forming an immobilized enzyme membrane on an element having plural ion-sensitive parts, shielding the immobilized enzyme membrane partly with a mask made of chromium, etc., and irradiating the immobilized enzyme membrane with a low-pressure mercury lamp, etc. emitting light shielded by the light-shielding part of the mask and having wavelength active to inactivate the enzyme, thereby effecting the partial inactivation of the enzyme. |
