Abstract
The invention provides fabrics that incorporate a cold-adapted trypsin derived from a fish or a crustacean, which trypsin inactivates viruses. The fabrics of the invention may be used in the production of various items of self-sterilizing protective equipment including gowns, sheets, curtains, surgical hats, surgical booties and protective facemasks.
Claims8
A material adapted to inactivate enveloped viruses present in an aqueous aerosol upon contact with the material, the material comprising a fabric and a non-specific protease associated with the fabric, wherein said non-specific protease is a cold-adapted trypsin with an activity of at least 0.04 au/hr/cm2 at a temperature of 16° C., and wherein said cold-adapted trypsin is derived from a fish or a crustacean, and wherein the protease is bound to the fabric by adsorption or by ionic or covalent bonding.
