The main research area of the Department of Biophysics is analysis and characteristics of the interaction of biologically active compounds with biopolimers (proteins, lipids), cell membranes and whole cells in relation to their potential application in biomedicine.  In our investigations we use a modern biophysical and physicochemical techniques like: fluorescence spectroscopy, electron paramagnetic resonance (EPR), Fourier-transform Infra-Red spectroscopy (FTIR), circular dichroism (CD), zeta potential and calorimetry techniques. Our investigations are aimed to understanding and describing the mechanisms responsible for the interaction of the studied compounds at the cellular and molecular level with an explanation of structural and functional dependencies.
