Michaela Kohlová Supervisor: prof. RNDr. Petr Solich, CSc. Consultants: prof. Maria de Conceição Branco Montenegro assoc. prof. Alice Santos-Silva Title of dissertation thesis: Development of new types of biocompatible haemodialysis membranes for separation of biomolecules This dissertation thesis was focused on the development, preparation, and optimization of flat sheet polysulfone membranes, which would meet the characteristics required for membranes used for haemodialysis treatment. The thin porous membranes were prepared by spin coating method, followed by phase inversion via immersion precipitation. The composition, as well as the preparation process of the membranes, were optimized, to obtain a membrane with good mechanical performance in flow conditions, adequate selective separation ability, and biocompatibility. The prepared membranes with the appropriate characteristics were modified with bioactive compounds to minimize oxidative stress and/or inflammation, which are common complications in haemodialysis treated patients. Three different modification approaches were used to prepare the bioactive..
