Abstract: The present invention provides a dense-coverage, adherent phosphorous-based coating on the native oxide surface of a material. Disclosed phosphorous-based coatings include phosphate and organo-phosphonate coatings. The present invention also provides further derivatization of the phosphorous-based coatings to yield dense surface coverage of chemically reactive coatings and osteoblast adhesion-promoting and proliferation-promoting coatings on the native oxide surface of a titanium material.

Abstract: An implantable device with a metal, metal alloy, metalloid, polymeric or ceramic surface and a phosphonic acid coating layer directly contacting the surface wherein the surface has hydroxyl groups covalently bonded to the acid groups of the coating layer and the phosphonate organic ligands are omega-functionalized.

Abstract: The present invention provides a process for providing on the surface of a substrate a chemically bonded, densely-packed, oriented organic acid-based mono-layer, the method comprising: (i) providing on at least a portion of said surface of said substrate a densely-packed, adsorbed oriented mono-layer comprising a plurality of at least one organic acid species wherein each of the organic acid species comprising said adsorbed mono-layer has at least one acid functional group associated with said surface of said substrate; and (ii) bonding to the surface of said substrate said surface-associated acid functional groups.

Abstract: The present invention provides increased adhesion between the native oxide surface of a material and adhesive material or tissue by providing a phosphorous-based coating layer comprising a plurality of omega-functionalized organo-phosphonate moieties bonded to the native oxide surface of a substrate by a phosphonate bond and a plurality of one or more coating moieties selected from the group consisting of inorganic, organic, or bioactive moieties, each said coating moiety being bonded to the omega-functional group of at least one omega-functionalized organo-phosphonate moiety by means of a member of the group comprising a metal complex and an organic polymer, and when bonded by means of a metal complex, the metal complex further characterized by being derived from a metal alkoxide reagent, and when bonded by means of an organic polymer, the organic polymer further characterized by being derived from an ionic or step-reaction polymerization which incorporates one or more of said omega-functional groups into sa
