Abstract: A composite article is prepared having in sequence a fibrous 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 such as enzyme. The surface treatment can be carried out by coating the surface with an inorganic oxide or by subjecting the surface to plasma treatment.

Abstract: A method for disinfecting a medical device comprising the steps of immersing a medical device in a hydrogen peroxide solution for a time sufficient to disinfect said device, decomposing any residual hydrogen peroxide by use of a catalytically effective amount of a protein capable of decomposing hydrogen peroxide, said protein being immobilized on a composite article, said composite article comprising in sequence a support, a layer of protein immobilizer compound, and a biologically active protein. The surface modification treatment is a gelled network of inorganic oxide particles or a plasma treatment.

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.

Abstract: An article and a method for cleaning a contact lens is disclosed, said method comprising providing a moistened non-woven fibrous web wherein the average fiber diameter is up to 50 microns, contacting and rubbing the lens with the fibrous web, and removing the lens from contact with the fibrous web.

Abstract: A composition is disclosed which includes the use of glyceryl monolaurate in combination with one or more other anti-microbial agents and, optionally an organic surfactant as a cleaning, disinfecting and preserving system which must be non-irritating and non-allergenic to body tissues. The composition is effective against a variety of microorganisms within a reasonable period of time, at concentrations that, if desired, can result in a visually clear solution. It is useful in a solution for cleaning, disinfecting and preserving contact lenses.
