Abstract
A composite article is prepared comprising in sequence a fibrous polymeric support which has been subjected to a surface treatment to provide binding sites thereon, a layer of a protein immobilizer compound, and a biologically active protein. The surface treatment comprises coating the support with a 2 to 500 nm thick layer of inorganic oxide or subjecting the support to a plasma treatment. The protein immobilizer can be a polymer or silane-functional compound. The biologically active protein can be the enzyme, catalase, which has use in decomposing hydrogen peroxide when disinfecting contact lenses.
