Abstract
An ion-selective electrode having an ion-selective membrane in direct contact with an electrical conductor is provided in which the membrane coats an uninsulated zone surrounded by insulation on the surface of a conductor which is coated with a layer of electrical insulation. The membrane overlays the insulation surrounding the insulation free zone and comprises a polymer which is generally of sufficiently similar composition to that comprising the electrical insulation layer so that it adheres to the insulation forming a membrane with increased structural strength. Embodiments of the electrode containing phosphatidylcholine in the ion-selective membrane have increased sensitivity.
