Abstract
The present invention relates to a pH buffered bioactive glass, and its preparation process and use. The pH buffered bioactive glass comprises SiO2, CaO, Na2O, and P2O5, and further comprises solid acidic particles or a Tris buffer solution. The pH buffered bioactive glass can regulate the pH of formulations comprising bioactive glass, and has a good therapeutic effect with a low dosage.
