Long-term implantation of voltammetric oxidase/peroxide glucose sensors in the rat peritoneum.
Methods for designing, fabricating, testing in vitro and in vivo, and improving chronically implantable oxidase/peroxide-type polarographic glucose sensors are described. Voltammetric means to evaluate oxygen supply to the sensor and to measure the nearby microcirculation with hydrogen washout techniques using the implanted glucose sensor are outlined. Because some peritoneally implanted sensors have, perhaps surprisingly, remained functional for months, such devices may prove with further development to be useful as the sensing components in artificial pancreatic beta cells for the control of diabetes.
