A urea biosensor was developed by immobilizing urease into an electropolymerized electroinactive polypyrrole (PPy) on a platinum electrode. This enzyme-immobilized PPy electrode showed a stable potential response to urea based on the pH response of the electroinactive PPy film electrode. The electro
A novel potentiometric biosensor for urea, based on the entrapment of urease into a polypyrrole film, has been developed via galavanostatic film formation. The electrochemical polymerization was achieved by the application of a current density of 0.5 mA cm-\* to a working platinum disc electrode for
