Abstract
Since a wide variety of microscopic living forms in contact with medical implant in human body are known to be sensitive and reactive to the surface topography, it is of active interest to optimize the implant surface of for desired integration. Ultrafast laser is a powerful tool for modifying the surface of medical implants, at the micro- /nano-scale, for either improving or limiting living tissues adhesion ability. Laser processing and living microorganisms’ response to laser texturing are discussed. Bacteria reduction and human cells adhesion at implant surfaces are reviewed in connection with ultrafast laser induced surface micro- / nanostructures.
