Solid contact ion sensor with conducting polymer layer copolymerized with the ion-selective membrane for determination of calcium in blood serum

A new solid contact ion selective electrode with intermediate conducting polymer (CP) layer formed by electropolymerization on a gold electrode of a bifunctional monomer, n-phenyl-ethylenediaminemethacrylamide (NPEDMA), which contains a methacrylamide group attached to aniline, is presented. Ion-selective membrane based on acrylated urethane polymer was shown to co-polymerize with the CP forming highly adhesive boundary. The designed ion-selective electrode was successfully used for determination of total calcium ion concentration in blood serum samples.
