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.
