Engineering of the Hydroxyapatite Cell Adhesion Capacity

摘要

The general adhesion theory is the fundament to explain cell attachment to a bioimlplant surface in a human body. Electrical potential of the surface could be employed to control attachment. The paper demonstrates that the electrical potential may be engineered due to hydrogenation of hydroxyapatite. Such the procedure enhance attachment of osteoblast and generation of tissue. The Sr and Si doped hydrohyapatite demonstrates higher ability to be engineered by hydrogenation in contrast with undoped and Ag doped materials.
