    Research on Bioglass carried out by the University of Modena and Reggio Emilia

    Il bio glass it is a glass whose chemical composition is very similar to that of bone tissue.
    This feature has allowed their use in orthopedics as implant material; the biocompatibility of these glasses is such as to make a direct anchoring with the bone tissue possible, thus improving the interactions that are generated between tissues and implant materials.

    In Modena, a group of researchers from Unimore, the University of Modena and Reggio Emilia have created a bioactive glass capable of maintaining bioactivity and inhibiting oxidative stress at the origin of inflammation caused by metal prostheses.

    The study "Cerium-doped bioactive 45S5 glasses: spectroscopic, redox, bioactivity and biocatalytic properties", was published by the prestigious Journal of Materials Science (ed. Springer), and was developed by Dr. Valentina Nicolini, by prof. Gianluca Malavasi, by prof.ssa Ledi Menabue and prof.ssa Gigliola Lusvardi of the Department of Chemical and Geological Sciences (DSCG) and by dr. Francesco Benedetti, prof. Sergio Valeri and dr. Paola Luches from the Department of Physics, Computer Science and Mathematics (FIM).

    Bioactive glasses are a class of materials already in use for some decades, for example, as additives to toothpaste and as coatings for metal prostheses.

    In the latter case, their function is to stimulate the cell proliferation of osteoblasts and therefore the growth of the bone which is deposited on the surface of the glass and replaces the glass which degrades with the result of stably anchoring the prosthesis to the bone.

    “In our studies - explains Prof. Ledi Menabue - we have modified the composition of a bioglass with the addition of cerium oxide, demonstrating that the bioglass maintains bioactivity and at the same time inhibits oxidative stress, thus reducing inflammation.

    A great made in Italy result.
