TOMSK, Oct 13 – RIA Tomsk. Scientists of Tomsk State University (TSU), together with colleagues from South Korea, have begun developing composite materials for next-generation implants that are replaced by body tissues; the project has received grants from both countries, the university's website reported Wednesday.
"A joint international project between TSU and Seoul National University Boramae Medical Center has won a bilateral grant competition from the Ministry of Science and Higher Education of the Russian Federation and South Korean Ministry of Science. <...> The researchers plan to synthesize magnesium-based materials with biocompatible inert coatings", – says the report.
It is specified that new composite materials are planned to be used to create bioresorbable implants, such as those which are gradually completely dissolved and replaced by body tissues.
According to TSU, the development of these implants is one of the main trends in the field of biomedicine. The implants require high biocompatibility, durability and a controlled rate of resorption so that the bone remodeling process can start quickly and have time to complete before the material is completely biodegraded.
"We will develop scientific and technological approaches to manufacture a new generation of medical magnesium alloys, hardened with nanoscale particles with modified inert coatings. This will ensure high indicators of physico-chemical, biological and physical-mechanical properties combined with controlled biodegradation", – project manager Ekaterina Marchenko is quoted as saying in the report.
It is added that TSU has been collaborating with Korean universities for 10 years in the creation of new biomaterials and biotechnologies. Scientists have published more than 20 joint scientific publications.
