Magnesium(Mg) is light, biocompatibility and has mechanical properties to natural bone. However, pure Mg severely corrodes in a physiological environment, which may result in fracture prior to substantial tissue hesling. Mg Surface was modified by depositing a thin polymeric thin film cotaining COOH, NH2 and OH groups through plasma polymerization of acrylic acid, ally amine and allyl alchol. -COOH function was favorable for bone-like apatite formation when compared with -NH2 and -OH. It was also concluded that a bone-like apatite formed COOH/Mg surface was more effective slowed down the degradable rate of the surface that another group. The results of cell proliferation revealed significantly enhanced cell proliferation and differentiation on the COOH/Mg and NH2/Mg surfaces than another surfaces. |
