COATED BIOLOGICAL COMPOSITION
A coated biological composition has a mixture of biologic material and a volume of a liquid protectant. The mixture of biologic material has non-whole cellular components or whole cells or combinations of the non-whole cellular components and whole cells, wherein the mixture is compatible with biologic function. The volume of a liquid protectant is intermixed with the mixture of biologic material, wherein the liquid protectant forms a coating externally enveloping each of the non-whole cellular components, if any, and each of the whole cells, if any, of the mixture of biologic material, to form the coated biological composition. The coated biological composition is frozen and thereafter thawed and then frozen a second time for storage or frozen at least once and thawed and stored under refrigeration above freezing, or frozen and thawed and then concentrated by drying, or while frozen without thawing lyophilized for ambient or room temperature storage.
Polypeptide and hyaluronic acid coatings

TWO COMPONENT ALPHATIC POLYURETHANE/POLYUREA/POLYASPARTIC COATING
A system and method for creating and coating a polymer-based coatings, in particular, a two-component aliphatic polymer-based coating with antimicrobial properties. The donning and coating of the polymer compound provides a protective layer on a surface that provides support and protection against diseases and infections for passing individuals. The polymer is composed of a two-part composition; the first part of the polymer made out of a combination of water, polylol, and paint additives, and the other part of the polymer made out of a combination of hexamethalyne, a catalyst, and an antimicrobial agent. The two-part polymer provides an antimicrobial layer on a surface in an effort to prevent the spread of infectious diseases.
