Biocompatible MgO Film on Titanium Substrate Prepared by Sol-gel Method
MgO film was prepared by a sol-gel method on titanium substrate for bioactive and antibacterial surface modification of osteo-implants. X-ray diffraction analysis shows that the gel film can be crystallized by the calcination at 400 °C. The MgO film is converted to Mg(OH)2 after ageing in air. The film is crack-free observed with scanning electron microscopy, and exhibits bioactivity by inducing the formation of apatite layer in the simulated body fluid test. It is also biocompatible with osteoblast cells and slightly antibacterial against E. Coli. The sol-gel MgO film would provide a facile surface modification method for biomedical titanium implants.
