Agnieszka Kaczor is a postgraduate researcher in the Faculty of Chemistry at Jagiellonian University in Krakow, Poland. Her scientific interests concentrate on the application of vibrational spectroscopy and multitechnique imaging to study biological samples. Recently, she has focused on studying changes in cells and tissues upon pathology development with the help of Raman and AFM imaging as well as theapplication of Raman optical activity to investigate bioactive compounds.Malgorzata Baranska is a professor in the Faculty of Chemistry at Jagiellonian University in Krakow, Poland. She focuses on research of plant and medical bioactive compounds by means of spectroscopic methods, particularly modern Raman techniques (i.e., Raman imaging and Raman optical activity). The new direction of her research is related to lifestyle diseases, their development and methods of curing. This research in various in vitro, ex vivo and in vivo animal models is conducted partly in the Jagiellonian Centre for Experimental Therapeutics (JCET).
