  Electric Breakdown in Liquids
Discharges in Water and Their Applications

Electrical discharges in liquids have been widely investigated for transient high voltage insulation and switching applications. Despite extensive efforts, the mechanism of breakdown initiation and formation of streamers are not completely understood. Regardless, streamers in water are an attractive means for water treatments. In our research we investigate both the physics of electrical breakdown in liquids and its possible applications.

  Plasma Medicine
Non-Thermal Plasmas for Medical Applications

Our research is focusing on possible therapeutic applications of non thermal plasmas. The primary objective is the investigation as a disinfectant for wounds and skin in general, and as a treatment modality for other skin diseases and conditions. The complexity of the plasma, which meets with the complex biological target, entails a manifold of possible interactions and synergies. Accordingly, we have combined the expertise of biologists, physicists and engineers to study plasma parameters, plasma chemistry and biochemistry.

  Biophysics of Pulsed Electric Fields
Immediate Response Mechanisms

The first, immediate response of exposures of cells and tissues by electric fields or plasmas is determined by physical processes. The often fast and brief mechanisms require diagnostic tools with temporal resolution shorter than the exposure, e.g. nanoseconds, and spatial resolutions comparable to the exposed object, e.g. single cells. On a larger scale these single cells responses add up to changes of the physical properties of tissues. The biophysical analyzes of these phenomena will be provided by our research.

  Dielectric Spectroscopy
Electrical Properties of Cells, Tissues and Materials

Dielectric properties of cells, i.e. the distribution of capacities and impedances, are crucial for a quantitative description of its interaction with electric stimuli. Accordingly, measurements and analysis of dielectric properties can describe or even predict cell-specific responses. Conversely, monitoring dielectric parameters after exposure of cells to electrical stimuli can reveal changes to cell morphologies, membrane structures and specific cell functions.

  Pulsed Power Engineering
Science and Technology of Short Electrical Pulses

The generation of discharges in water and the design of systems for exposures of cells and tissues to ultrahsort high voltage pulses, requires a unique skill set known as Pulsed Power Engineering. With respect to application and the characteristic of the sample that needs to be exposed we design generators, develop diagnostic methods, analyze and evaluate exposure conditions. We also study the changes of materials and material properties under the often extreme conditions.
