The Department of Biomaterials Technology is a new (established in February 2021, from the transformed Department of Biomaterials, whose founder was Prof. Andrzej Zieliński), currently the team consisting of: Prof. Andrzej Zieliński, dr inż. Magdalena Jażdżewska, dr inż. Beata Majkowska-Marzec, dr inż. Alicja Stanisławska, dr inż. Michał Bartmański, dr inż. Marcin Wekwejt, mgr inż. Magda Dziaduszewska, M.Sc. Dorota Rogala-Wielgus and dr hab. eng. Beata Świeczko-Żurek - head of the Department.
The area of the research in the field of biomaterial engineering, that the employees deal with are: modifications of titanium implants in the direction of their bactericidal activity, greater bioactivity and corrosion resistance (microporous oxide coatings, hydroxyapatite and nanohydroxyapatite, with the addition of nanometals, pH-sensitive, composite based on carbon nanotubes). Other research areas include: the degradation processes of various types of implants, with particular emphasis on the bacterial environment, which led to the patenting of a new model suspension of hospital bacteria, the development of a laser technique for modification of the surface of titanium implants, and the development of bone cements.
The biomaterial group has several publications, many patents, implementations, projects (IDUB, NCN, NAWA), to which contributed intensive cooperation with companies (Aesculap), medical universities in Lublin and Gdańsk, AGH, Lodz University of Technology, Koszalin University of Technology, Specialist hospitals in Kościerzyna and Inowrocław, as well as with European universities in Germany, France, Iceland, Finland and Israel.
