A biodegradable and treatment accelerating polymer for bone implants developed in Tomsk

Scientists at the Scientific Centre of Tomsk Polytechnic University (TPU) have managed to obtain a polymer that can be used in regenerative medicine. It dissolves in the body over time and generates an electric charge under mechanical action, which stimulates cells of the body and thus helps the recovery, the press service of the university informs.

It became possible in the course of development of the material to combine two important for practical application properties: the polymer is biodegradable and is a piezoelectric (dielectric) at the same time.

Such a hybrid polymer, which is capable of producing electricity and then eventually dissolves into living tissue, could be used as a material for bone implants, to replace bone defects, restore nerves, and as a dressing for wounds, the university claims. The scientists in Siberia managed to significantly improve the mechanical properties of the polymer in comparison with its existing counterparts. Namely it stretches better, which is important if you use it, for example, to make wound dressings.
