Mesoporous Strontium-Doped Phosphate-Based Sol-Gel Glasses for Biomedical Applications.

Mesoporous phosphate-based glasses have great potential as biomedical materials being able to simultaneously induce tissue regeneration and controlled release of therapeutic molecules. In the present study, a series of mesoporous phosphate-based glasses in the PO-CaO-NaO system, doped with 1, 3, and 5 mol% of Sr, were prepared using the sol-gel method combined with supramolecular templating. A sample without strontium addition was prepared for comparison.
