An amperometric enzyme electrode for monitoring brain glucose in the freely moving rat.
Brain glucose concentration was measured with an amperometric enzyme electrode using glucose oxidase (EC 1.1.3.4) irreversibly adsorbed onto an organic conducting salt. The responses of the electrode and its stability both in vitro and in vivo are described. Parellel changes in brain glucose and blood glucose (measured in samples from an implanted intra-atrial cannula) following injections of insulin are reported.
