Structure, properties and functions of biological macromolecules. Electrostatic characteristics of complex protein structures. Mechanisms of interactions between ions and biomolecular structures (biopolymers). Biopolielectrolytes. Electrical conductivity of biopolymers. Electron transfer through proteins. Electron transfer in DNA. Basics of bioelectromagnetism. Electrical signals in cells. Cell membrane as electrical system (resistance and capacitance of membrane, voltage gated ion channels). Action potential. Excitation and propagation of nerve signals. Electrical models of neurons. Biosensors (technologies and applications). Interaction of biological molecules with semiconductor nanoparticles. BioMEMS/BioNEMS (materials and devices). Devices based on bioelectronic interfaces (ISFET, CHEMFET). Part of the course takes place through individual research and study work in the field of bioelectronics. The study and research work is based on active study of primary scientific sources, new model development, perform in silico experiments, data processing of numerical simulations, as well as writing a paper in the narrow scientific field within the topic of the doctoral dissertation.
