Differently deposited amino functionalized surfaces were compared regarding their physico-chemical surface properties in connection with cell biological response. The nitrogen containing coatings were prepared by microwave or radio frequency discharges using allylamine and ethylenediamine as precursors, respectively, or by means of radio frequency magnetron sputtering of nylon 6.6.
Closed pinhole-free polymer films resistant to hydrolysis and delamination were detected in most cases. Although the density of primary amino groups differs in dependence on the method of preparation no direct correlation was found between the densities of primary amino groups and an enhanced cell growth.
