A composition comprising a doubly conjugated chitosan polymer or oligomer, and a functionalized metal work piece including the doubly conjugated chitosan polymer or oligomer.

Antimicrobial with modified-chitosan functionalization via dopamine linkage

A method of photografting organic molecules to a metal oxide comprising: (a) contacting a substrate having a metal oxide layer on a surface thereof with an acrylate, derivative thereof or a photolabile functional group; and (b) exposing the metal oxide layer and the acrylate, derivative thereof or photolabile group to UV or visible radiation to form covalent bonds between the metal oxide and the acrylate, the derivative thereof or the photolabile.

Method of photografting organic molecules to metallic substrates and devices having photografted organic molecules

A method of preparing a modified-metal surface. The method includes preparing a solution of a phosphorous-based acid in a solvent; immersing a strip of the metal work piece into the solution of the phosphorous-based acid; immersing a strip of a reference metal into the solution of the phosphorous-based acid; supplying a voltage for a duration of time to prepare a phosphorous acid-modified metal work piece; removing the phosphorous acid-modified metal work piece; cleaning and drying the phosphorous acid-modified metal work piece; applying a chitosan solution to the surface in order to attach chitosan/modified chitosan to the phosphorous acid based modified surface; prepare the modified-metal surface; and cleaning and drying the modified-metal surface.

Electrochemical attachment of phosphonic acids to metallic substrates and antimicrobial medical devices containing same

A method of preparing a modified-metal surface by attaching a phosphorous-based acid to a surface of a metal: preparing a solution of the phosphorous-based acid in a protic solvent; immersing a strip of a metal work piece into the solution of the phosphorous-based acid, immersing a strip of a reference metal into the solution of the phosphorous-based acid, supplying a voltage for a duration of time, removing the metal work piece, cleaning the metal work piece, and drying the cleaned metal work piece under an inert atmosphere to obtain a modified metal work piece.

Electrochemical attachment of phosphonic acids to metallic substrates and osteoconductive medical devices containing same

Articles having functional surfaces, for example antimicrobial functional surfaces, are prepared by methods comprising anodization. Organophosphorous compounds are deposited on a surface by methods comprising anodization, followed by attaching functional compounds, functional oligomers or functional polymers. Alternatively, functional organophosphorous compounds, functional oligomers or functional polymers are deposited on a surface by methods comprising anodization.

Functional surfaces

Devices are provided which are functionalized to include surface regions having anti-infective agents. Methods are provided for functionalizing various material surfaces to include active surface regions for binding anti-infective agents. Methods are provided by which anti-infective moieties or agents are bonded to functionalized surfaces.

Anti-infective functionalized surfaces and methods of making same

Disclosed in certain embodiments is a composition comprising a biological material and transition metal atoms selected from the group consisting of Group IVB, Group VB, Group VIB of the Periodic Chart and a combination thereof, bound to a surface of the biological material.

Surface modified biological materials

Articles having metal, metalloid or non-metal surfaces containing an antimicrobial layer comprising antimicrobial oligomers or polymers are suitable for use in medical devices, sanitary surfaces and other applications. Antimicrobial layers contain an organophosphorus layer deposited on an article surface and antimicrobial oligomers or polymers bonded to the organophosphorus layer.
