Abstract
In this invention, a separative structure of the ion-selecting electrode is applied to fabricate the dual type potentiometric biosensor for creatinine detection. According to the fabrication process, the creatinine enzyme is immobilized onto a conductive layer of a substrate of pH sensing membrane and ammonium ion-selecting membrane. The conductive layer provides with a sensing region and a non-sensing region. A conductive line is extended from the conductive layer for using as an external electrical contact point. The dual type potentiometric creatinine biosensor was fabricated by using the enzyme immobilization method onto the surface of the selecting membrane of sensing membrane of pH sensing electrode and creatinine sensor.
