9. A sensor array made by a process comprising:
-
providing a substrate comprising a plurality of reference electrodes and a plurality of gel-coated electrodes, wherein each of the gel-coated electrodes are coated with a gel layer;
contacting each Of the gel layers with a different charged or polarizable ionophore;
applying an electric field to each gel layer sufficient to migrate the ionophore into the gel layer;
coating each gel layer comprising the ionophore with a polymer layer comprising the same or a different ionophore; and
coating each polymer layer with a protective layer. - View Dependent Claims (10, 11)
