Biography
Dr. Barbara Krajewska is the Professor of Chemistry in Jagiellonian University. Her scientific interest is in (bio)polymeric functional materials and their bio-applications. These include areas such as biomedical materials, separation processes, biosensors, and importantly, immobilization of enzymes. The utilization of enzymes is special in that it is one of chief present strategies towards environmentally benign and energy- and materialsaving chemical processes. The polymer and enzyme she concentrate on are chitosan and urease. Chitosan, a polyaminosaccharide from renewable resources offers a unique benefi cial set of bio-characteristics. Urease by contrast, is an enzyme of crucial importance in medical, analytical and novel engineering areas. She study chitosan as a biomaterial and as a urease immobilization support, also urease in its native and chitosan-immobilized form, and interfacial phonemena taking place in the chitosan-urease system.
