Abstract: 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.

Abstract: 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.

Abstract: 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.
