Abstract
The invention relates to an ion-selective electrode and to a procedure for producing the electrode. The electrode is a single-piece all-solid-state electrode comprising a conducting or semiconducting solid substrate (6) coated with a composite membrane (4). The electrode is produced by dissolving a conjugated polymer or oligomer together with the components of a conventional ion-selective membrane to produce a solution, applying this solution to an electronically conducting or semiconducting substrate and allowing the solvent to evaporate, with the result that a composite membrane is formed on the substrate.
