  • Publication number: 20190142317
    Abstract: Disclosed are implantable glucose sensors having a biostable surface. The implantable glucose sensor includes a glucose detector and an enclosure defining a boundary between an internal space and an external space. The enclosure includes a semipermeable biointerface film containing a base polymer and a biostabilizing additive. The semipermeable biointerface film has a biostable surface and is permeable to glucose. The working electrode is disposed inside the internal space, and the biostable surface faces the external space or faces both the internal and the external spaces. Also disclosed are methods of preparation of the semipermeable biointerface films adapted for use in the implantable glucose sensors. Further, disclosed are methods of monitoring glucose levels in a subject through the use of an implantable glucose sensor. The implantable glucose sensor may be an implantable electrochemical glucose sensor, in which the glucose detector is a working electrode.
