Abstract

Protein-polymer composite materials are provided according to embodiments of the present invention that include an admixture of a polymer resin, a surfactant and a non-aqueous organic solvent. An aqueous solution containing bioactive proteins is mixed with the admixture. The emulsion is mixed with a crosslinker to produce a curable composition. The curable composition is cured, thereby producing the protein-polymer composite material that is useful for facilitating removal of bioorganic stains.
