IMPLANTABLE ANALYTE SENSOR

摘要

An insertable analyte needle sensor (10), comprising a set of fine wires (12) positioned together and a dielectric material (22) covering a substantial portion of the fine wires but defining an opening (18) filled with at least one partially permeable membrane (36). The wires (12) may be treated with a gas plasma to facilitate membrane adherence. One membrane layer (30) may comprise sulphonated polyethersulphone coated with silane.
