Abstract
Because of the excellent mechanical properties, biocompatibility and reasonable prices, biomedical metallic materials are widely used in the manufacture of vascular stents, heart valve membrane, artificial joints and other body implants. However, the physiological environment in the body is very complex, the long-term embedding of the metal implants may result in corrosion or some nonspecific effects. The properties of medical metal surfaces may decay, which can cause serious injury to human body. By means of the self-assembled monolayer(SAM) technology, the physical and chemical properties of the medical metal surfaces can be modified, and through the SAM medium, some functional materials can be grafted on the metal surfaces, which can largely improve the stability and compatibility of implants in the body, and find wide applications in promoting cell adhesion, improving hemocompatibility, inhibiting bacteria growth, and constructing drug delivery coatings. This paper reviews the progress in the application of SAM in biomedical metallic materials.
