Study Findings on Apatites Are Outlined in Reports from Chinese Academy of Science (Magnesium substituted hydroxyapatite coating on titanium with nanotublar TiO2 intermediate layer via electrochemical deposition)

By a News Reporter-Staff News Editor at Science Letter -- Current study results on Apatites have been published. According to news originating from Shenyang, People's Republic of China, by NewsRx correspondents, research stated, "Hydroxyapatite (HAp) coatings doped with magnesium ion is an attractive method to improve the biocompatibility and biodegradability of HAp coatings. In this paper, we used electrochemical deposition to study the production of magnesium-doped HAp (MgHAp) coatings onto pure titanium with anodized titanium oxide (TiO2) nanotubes as intermediate layer."

Our news journalists obtained a quote from the research from the Chinese Academy of Science, "The morphology and composition of coatings were studied by scanning electron microscopy, energy-dispersive X-ray spectroscopy, X-ray diffraction, and Fourier-transform infrared spectroscopy. Results indicated that Mg was uniformly distributed in the coatings, and each coating was found to be 21 pin thick. With Mg2+ incorporation, Ca2+ was substituted by Mg2+ in the MgHAp coating, thereby reducing apatite crystallinity and weekly increasing bond strength. The bioactivity and corrosion resistance of the coatings were improved in simulated body fluid and polarization tests, respectively."

According to the news editors, the research concluded: "Cell culture tests indicated that the magnesium-substituted coatings had good biocompatibility and no adverse effect."
