Abstract

The initial action of an enzyme (for instance a catalase) on a substrate (for instance hydrogen peroxide) can be retarded by distributing a solution of the substrate across a primary and a secondary chamber and by immobilizing the enzyme on a surface in the secondary chamber. The subsequent decomposition of the substrate by the enzyme is not retarded. This method can be used in the disinfection of contact lenses by hydrogen peroxide. The surface on which the enzyme is immobilized can be formed from a nylon sheet. High levels of enzyme can be bound to a nylon sheet in which the nylon molecules have been subject to a shear during the formation of the sheet, in order to orientate the molecules within the sheet.
