However, under certain circumstances BGs such as the well-known 45S5 Bioglass® (composition in wt%: 45.0 SiO2, 24.5 Na2O, 24.5 CaO, 6.0 P2O5) act cytotoxic due to a strong increase in pH caused by a burst release of sodium ions. Thus, the development of new bioactive glasses with low- or free- alkali content is a key part of our work. Our focus is the fundamental understanding of composition-structure-property relationship of these new materials aiming to tailor new compositions for bone tissue engineering .
