Abstract
Improvements to the biocompatibility of medical implant biomaterials have a great significant impact toward improving the safety of the implants. Ultrafast lasers have been widely used in biomedical sciences for their ability to produce micro/nano structures that improve the biocompatibility of biomaterials. In this paper, mechanisms of interaction between cell and biomaterials are briefly introduced. The effects of surface topography on cell adhesion, migration, multiplication and differentiation are summarized according to the effect of surface structure on the biocompatibility. The disadvantages of current laser microfabrication technologies in biomaterials are identified and suggestions for further development are provided.
