China develops bioglass that helps bones heal themselves

Chinese scientists have just announced a breakthrough research on 3D printable bioglass material, opening up new prospects in treating and restoring bone damage.

Research conducted at Dalian University of Technology, China, shows that the new bioglass material is better able to support bone cell growth than conventional glass and commercial bone graft materials currently on the market.

Professor Huanan Wang, the study's lead author, said many orthopedic surgeries require custom bone grafts, especially in cases of facial and skull bones. The technology's main advantage is its ability to create bone structures that precisely fit the required shape and size.

Not only that, the bioglass production process is completely “green”, not using toxic chemicals and extremely high firing temperatures like traditional methods. Instead, scientists combine oppositely charged silica particles with calcium and phosphate ions to form a printable bioglass gel.

Test results on rabbits showed that after 8 weeks, most bone cells had grown on the bioglass structure, while conventional glass showed almost no bone cell growth.

Professor Wang stressed that further research and testing on larger animals is needed before applying it to humans. However, with the initial positive results, this technology promises wide applications not only in medicine, but also in other industries such as machinery, energy and chemicals.
