Abstract
A substrate or coating is provided that includes a lipase with enzymatic activity toward a component of a fingerprint. Also provided is a process for facilitating the removal of fingerprints is provided wherein an inventive substrate or coating including a lipase is capable of enzymatically degrading of one or more components of the fingerprint to facilitate fingerprint removal from the substrate or said coating. Applying heat to the substrate or coating increases the rate of fingerprint removal.
Claims11
A method of facilitating the removal of a fingerprint on a substrate or a coating comprising:
- providing a substrate or a coating;
- associating a lipase with said substrate or said coating such that said lipase is capable of enzymatically degrading a component of a fingerprint, and
- facilitating the removal of a fingerprint by vaporization from the lipase associated substrate or coating when contacted by a fingerprint.
