Abstract

A method for coating a solid surface with a recombinant spider silk protein capable of forming polymeric, solid structures is provided. The method is comprising the following steps: exposing the solid surface to an aqueous solution of the recombinant spider silk protein and thereby forming a surface layer of the recombinant spider silk protein adsorbed on the solid surface without formation of covalent bonds between the recombinant spider silk protein and the solid surface; and further exposing the surface layer of the solid surface to an aqueous solution of the recombinant spider silk protein and thereby forming an assembled silk structure layer of the recombinant spider silk protein on the surface layer; wherein the method does not include drying-in of spider silk protein.
