Iranian researchers at Biomaterials Research Group of Materials Engineering Department, affiliated to Isfahan University of Technology, have built biocompatible materials, using metal alloys, which is resistant to corrosion and matches the bone.

To slow down the initial biodegradation rate of magnesium alloy, crystalline nano-sized bioactive glass coating was used, ISNA reported.

"The present study is aimed at developing a new generation of magnesium-based implantable elements using one type of nanostructure coating to help the recovery of bone lesion and minimize the side-effects of these elements," said Ramin Rajaie, a graduate student in materials engineering and author of the study.

Rajaie said the two-layer nanostructure coating is used in this study, which boosts resistance to corrosion and creates more biocompatibility.

The body cells do not differentiate between the biocompatible glass used in the coating and in the mineral segment of the bone due to their chemical similarity.

Results show that this process will enable the development of implants in the later stage of bone healing.

Using the proposed biodegradeable material, no secondary surgery is needed to remove the implanted material after full recovery. The method reduces the risk of bleeding and infections after surgery.
