Treatment of biological material containing living cells using a plasma generated by a gas discharge

摘要

In order to treat a biological material (1) containing living cells with a plasma (4) generated by a gas discharge at atmospheric pressure (9) an electrode (3) is arranged at a distance to the biological material (1). Further, a solid body dielectric (2) is arranged between the electrode (3) and the biological material (1), directly in front of the electrode (3) and at a distance to the biological material (1). Then a high alternating voltage consisting of separated high voltage pulses of alternating polarity is applied to the electrode (3) for igniting and maintaining a dielectric barrier gas discharge within a region between the dielectric (2) and the biological material (1).
