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