Abstract

For the first time Self-Assembled Monolayers (SAMs) were formed on nitinol and characterized. Factors which can affect the formation of SAMs such as head groups, chain length, and tail groups were varied and analyzed to form the most stable and strongly adhered monolayer on the surface. Since an alloy is being studied, the formation of SAMs was also studied on nickel and titanium oxide, the components of the nitinol surface. After data was collected by infrared spectroscopy (IR), atomic force microscopy (AFM), matrix-assisted laser desorption ionization mass spectrometry (MALDI), and contact angle measurements on the modified substrates. In the long term, the formation of strongly adhered self-assembled monolayers may form an effective interface between the biomaterial, nitinol, and the human body.
