Application of surface modification in biomedical materials research

In this paper, the applications and qualifications of biomedical materials are introduced. In regard to the hard tissue implants, the biocompatibility can be improved by preparing various bio- ceramic and bio- glass coatings. In view of this, the principles, characteristics, and applications of surface modi. cation (plasma spraying, electrostatic spray deposition, micro- arc oxidation, pulsed laser deposition, sol-gel deposition, and magnetron sputtering) in biomedical materials are reviewed. In addition, the research direction of improving biocompatibility by surface modi. cation is presented.
