Potentiodynamic techniques (linear sweep, cyclic and pulse voltammetry), potentiostatic and galvanostatic techniques, as well as impedance spectroscopy, are used to study the thermodynamics and kinetics of biologically relevant redox transformations.
Ongoing research:
Biosensors
- Investigation of enzyme redox potentials, rate constants of enzymatic reactions, ligand interactions.
- Study of natural/synthetic bioactive substance redox transformations and their antioxidant and antiradical activity.
- Study of new anticancer drug redox transformations.
- Development of new electrochemical biosensors, especially for toxic materials.

Biomaterials
- Synthesis of new biomaterials with potential biomedical applications: electroconductive and redox active polymers (e.g. polyaniline) and biomacromolecules (e.g. collagen, starch). Electrochemical investigation of their antioxidant activity and spectroscopic characterization.
- Investigation of the antioxidant activity of new hybrid nanomaterials (e.g. polyaniline + phenolic acids) which show higher activity than pure components due to their synergistic effect. Optimization of synthetic conditions that affect structure and morphology and therefore their antioxidant activity.
