Abstract
A specifically reactive polymeric composition comprising an organic hydrophobic polymeric substrate with a specific protein reactive group pendant therefrom is disclosed. The protein reactive group is a free group of a hydrocarbon chain which has one end thereof absorbed into the surface of said substrate, said protein reactive group being bound to said hydrocarbon chain via an ionic group. An electrode coated with a layer of the specifically reactive composition provides, in conjunction with a reference electrode, an electrically sensitive system for measuring change in concentration of a compound in solution where said compound reacts selectively with the composition.
