Cell adhesion on biomaterial surfaces with nanocomposite oxide coatings

摘要

Deposition of functional coatings is one of the most optimal ways of surface modification enabling an efficient control of stoichiometry, impurity elements, functional groups and surface charges. Nano-composite coatings based on Al, Zr, Ti oxides exhibit unique properties: high induetivity, density, bio- and chemical inertness [1-3], which are very important for subsequent implant and tissue engineering applications. Corrosion is one of the major processes that cause problems when metals and alloys are used as implants in the body [4]. Corrosion of implants in the aqueous medium of body fluids takes place via electrochemical reactions [5], and it is necessary to understand the electrochemical principles that are most relevant to the corrosion processes.
