title: The development of an implantable electrochemical glucose sensor: response to glucose in bovine serum ultrafiltrate.
abstract: A glucose sensor based on organic oxidation reactions at a platinum electrode is being developed as the key component for an implantable artificial beta cell for diabetic patients. Sensitivity of a membrane-covered platinum electrode to changing glucose concentration in bovine serum ultrafiltrate has been demonstrated, with current response as high as 60 microamperes per 100 mg/dl change in glucose concentration. Reproducibility of measurements probably will depend on satisfactory mechanical assembly of the membrane-electrode combination. An approach to selectivity based on multiple current measurements is suggested.
