| Abstract: | A glucose enzyme electrode was constructed by using a Pt micro-discelectrode covered with a crosslinking enzyme membrane of glucose oxidase (GOD), the current response of the electrode was measured. The effect on the response of enzyme-immobilizing conditions such as the contents of GOD, carrier protein and crosslinking reagent was studied. By comparison, a favorable procedure was suggested for making the enzyme electrode and the sensitivity of the prepared electrode was examined in the test solutions with various pH values to provide the optimum for the electrode operation. |
