Bioactive coatings that include a base and a protein associated with the base for actively promoting the removal of organic stains are provided. In aspects, bioactive coatings that are stabilized against inactivation by weathering are provided including a base associated with a chemically modified enzyme, and, optionally a first polyoxyethylene present in the base and independent of the enzyme. The coatings are optionally overlayered onto a substrate to form an active coating facilitating the removal of organic stains or organic material from food, insects, or the environment.

Compositions for facilitating the removal of a fingerprint

Provided are methods and compositions for self-cleaning that include a digestive protein capable of decomposing stain forming molecules, a substrate applied to a solid surface, and a linker moiety bound to an outer surface of said substrate and an active group of said digestive protein, said linker moiety between said protein and said substrate and covalently linking said protein to a surface of said substrate by an amide bond, the linker moiety between a free amine of said protein and said outer surface of said substrate wherein the digestive protein forms a layer on a surface of said substrate such that the digestive protein is surface exposed for reaction with a stain.

Biofunctional materials

Bioactive protein-polymer compositions for stain removal

Bioactive coatings that are stabilized against inactivation by weathering are provided including a base associated with a chemically modified enzyme capable of enzymatically degrading a component of an organic stain, optionally a lipase or a lysozyme, and optionally a first polyoxyethylene present in the base and independent of the enzyme. The coatings are optionally overlayered onto a substrate to form an active coating facilitating the removal of organic stains or bacterial organic material.
