The Biomaterials for Medical Applications Group focuses on the development and optimization of metallic materials for medical use. We are working on biodegradable metals, particularly magnesium, iron, and zinc alloys, which are used in temporary implants such as fixation screws, pins, and stents. We are developing new alloys, such as beta titanium alloys with improved biomechanical compatibility and enhanced corrosion resistance. We are also working on surface modifications of existing alloys to improve osseointegration and antibacterial properties. We use nanostructuring, microtopography modifications, and the deposition of bioactive layers, such as apatites. To achieve an antibacterial effect, we incorporate elements such as silver, copper, and zinc. As part of the development of new custom-made materials, we utilize additive manufacturing (3D printing) technologies that enable, among other things, the controlled creation of porous systems that mimic the structure of human bone. We are also developing sensors for real-time monitoring of implant condition, thereby contributing to the advancement of smart biomaterials.
