Method of surface coating devices to incorporate bioactive molecules

摘要

A first embodiment is a coating for a surface comprising an electrostatic self-assembly creating one or more coating layer(s); (i) wherein one or more high molecular weight bioactive molecule(s) is bound to a protein carrier wherein said protein carrier or said bound bioactive molecule is further bound to one or more of said coating layer(s) and/or (ii) wherein one or more low molecular weight bioactive molecule(s) is/are incorporated within one or more of said layers or later introduced to said layer or layers by post-treatment. A second embodiment is a method of coating a surface comprising introducing said surface into a solution of one or more positively charged water-soluble polyelectrolytes at a pH ranging from about 2 to about 12 and at a temperature ranging from about 4° C. to about 80° C. and incubating said surface for about 0.5 to about 60 minutes; Rinsing said surface with said buffer solution or water to remove weakly bound material on said surface and dry by means known to one skilled in the art; Introducing said surface into a solution of one or more negatively charged water-soluble polyelectrolytes at a pH ranging from about 2 to about 12 and at a temperature ranging from about 4° C. to about 80° C. and incubating said surface for about 0.5 to about 60 minutes; and Rinsing said surface with said buffer solution or water to remove weakly bound material on said surface and passively or actively drying said surface.
