What is it about?
Bioactive glasses are able to bond to bone through formation of hydroxyapatite in body fluids. However, because of their poor strength their use is restricted to non-load-bearing applications. Addition of nitrogen has been found to enhance properties of oxide glasses. This paper reports on new oxynitride glasses and their mechanical properties and bioactivity. N increases hardness and elastic modulus as a result of extra crosslinking in the structure of the glass network. Optimisation of the N content allows tailoring of different levels of bioactivity.
