New material for implants may kill bacteria without antibiotics

November 2, 2019  14:14

Scientists of NUST “MISiS” together with European and American colleagues developed a new material for medical implants, which simplifies recovery after fractures.

According to Rossiyskaya Gazeta, the new material uses platinum and iron nanoparticles, thanks to which artificial bone can destroy up to 98% of harmful bacteria. This means that when using such implants, the risk of developing an infection after surgery will be significantly reduced.

As statistics noted, a bacterial infection occurs after implant placement in 1-4% of cases. The risk of developing an infection rises to 30% in the case of a complex fracture. Antibiotics are used to fight infection. But there are always risks that the infection will become resistant to antibiotics or there will be an allergic reaction. In some cases even repeated surgery is required due to infections.

A new material with platinum and iron nanoparticles in 8-12 hours destroys 98% of the harmful bacteria surrounding it. It can cope with staphylococcus, E. coli, Klebsiella pneumoniae. By the way, the immune system and lymphocytes do not suffer.

Scientists plan to conduct full-fledged tests of new implants on animals in the near future.
