    • A small diameter flexible electrode designed for subcutaneous in vivo amperometric monitoring of glucose is described. The electrode is designed to allow “one-point” in vivo calibration, i.e., to have zero output current at zero glucose concentration, even in the presence of other electroreactive species of serum or blood. The electrode is preferably three or four-layered, with the layers serially deposited within a recess upon the tip of a polyamide insulated gold wire. A first glucose concentration-to-current transducing layer is overcoated with an electrically insulating and glucose flux limiting layer (second layer) on which, optionally, an immobilized interference-eliminating horseradish peroxidase based film is deposited (third layer). An outer (fourth) layer is biocompatible.
    • 描述了设计用于皮下体内电导率监测葡萄糖的小直径柔性电极。 电极被设计成允许“一点”体内校准,即即使在血清或血液的其它电反应物质的存在下也能在零葡萄糖浓度下具有零输出电流。 电极优选为三层或四层,其中层叠在聚酰胺绝缘金线的尖端上的凹槽内。 第一葡萄糖浓度 - 电流转导层用电绝缘和葡萄糖通量限制层(第二层)涂覆,其上任选地沉积固定的干扰消除辣根过氧化物酶基膜(第三层)。 外(第四)层是生物相容的。
