1. A process of modifying the surface properties of a surface, which process comprises:
- applying alternative, monomolecular, successive layers of first and and second materials to a surface to be modified, the first material comprising avidin and the second material comprising a noncovalent, biotin-modified extender, one of the materials reacted to the surface, and, thereafter, at least one additional layer of each of the first and second materials alternated, secured and reacted to the underlying layer, to provide a surface with the first or second material as the top surface layer thereon.

Abstract
A multiple-layer process for applying, in alternate, successive layers, the protein, avidin, and a biotin-containing extender material to a solid surface to modify the properties of the surface and to the multiple-layer product so prepared.

21. A monomolecular-layering process of modifying the surface properties of a substrate surface of a polymer, which process comprises:
-
(a) applying a layer of a biotin-N-hydroxysuccinimide ester as a biotin-extender material to the surface of a polymer, to react the biotin-N-hydroxysuccinimide to the surface of the polymer; (b) washing the polymer surface to remove unreacted biotin-N-hydroxysuccinimide; (c) applying a layer of avidin to the washed polymer surface, to react the avidin with the biotin-N-hydroxysuccinimide extender material; (d) washing the reacted surface to remove unreacted avidin; (e) applying to the washed avidin surface a layer of a caproylamidobiotin NHS or RNase as a biotin-extender material; (f) washing the reacted surface to remove unreacted biotin-extender material; and (g) recovering the polymer having multiple layers, with the top layer composed of a biotin-extender material. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28)
