A bioactive glass will reduce inflammation caused by metal prostheses
A new “bioactive glass” will be able to reduce inflammation following the implantation of a metallic prosthesis. The bioactive glass was developed by researchers from the Department of Chemical and Geological Sciences (DSCG) and the Department of Physics, Computer Science and Mathematics (FIM) at the University of Modena and Reggio Emilia.
Bioactive glass is a material currently used in prostheses to stimulate bone growth and anchor the bone to the metal structure, but a possible side effect is the inflammation of surrounding tissues, due to oxidative stress.
The Italian researchers have studied a chemical modification of the bioglass by adding cerium oxide, a ductile metal that, thanks to its properties, can at the same time keep the compound biologically active and inhibit oxidative stress, thus reducing inflammation.
The study, published in the prestigious Journal of Materials Science, has aroused considerable interest in the international scientific community, so much so that it has been included among the finalists of the “Cahn Prize 2017”, launched by the specialist publisher Springer.
