Abstract
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.
Claims6
A composition for facilitating removal of a fingerprint from a surface, the composition comprising:
- a substrate or a coating formed of an organic crosslinkable polymer resin;
- and
- a lipase capable of enzymatically degrading a fat or oil component of a fingerprint, said lipase associated with said substrate or coating, wherein said lipase is uniformly dispersed in said substrate or coating in protein aggregates having an average diameter of 10 micrometers or less.
