Nickel-containing alloy oxides, can be modified with self-assembled monolayers under mild, solution deposition conditions. These monolayers are strongly-adhered and mechanically stable under organic and biological conditions. This study is important because previous monolayer formation on stainless steel, and other nickel containing surfaces has required reduction of the metal oxide surface to metal by electrochemical methods. This method allows for covalent attachment of monolayers to the native oxide surface. Further, the tail groups of these monolayers can be used to control the surface properties such as hydrophobicity. Finally, methyl-terminated monolayers on metal alloy oxide surfaces reduce non-specific cellular adhesion more than hydrophilic surfaces.
