文摘

Cellular adhesiveness on a Ti surface was enhanced by a focused laser treatment. Focusing the beam leads to a laser-induced plasma on the target surface. A thin layer of TiO2 was formed on the laser-treated substrate. The resulting TiO2 layer suppressed the adsorption of the contaminant carbon. Differentiation of the osteoblast-like cells was not facilitated by the treatment.
