## Abstract The amperometric biosensing of aromatic amines using a composite glucose oxidase (GOD)βperoxidase (HRP) biosensor in reversed micelles is reported. Rigid composite pellets of graphite and Teflon, in which GOD and HRP were coimmobilized by simple physical inclusion, were employed for the

During the continuing rapid daelopment of analytical methods based on immobilized enzymes, several techniques have been described for the determination of glucose. For example, glucose oxidase (E.C.1.1.3.4) entrapped in polyacrylamide gel was used by Updike and Hicks in two methods. In one case [l]
The glassy carbon electrode (gce) and highly oriented pyrolytic graphite (hopg) were electrochemically anodized at a potential of +2 .O V (vs. Ag/A8CI) to create active sites and to improve the adsorption of glucose oxidase (GOD) and flavin adenine dinudeotide (FAD) on the electrode surfaces . The G
