TREATMENT OF BIOLOGICAL MATERIAL CONTAINING LIVING CELLS USING A PLASMA GENERATED BY A GAS DISCHARGE

摘要

According to the invention, in order to treat a biological material (1) containing living cells using a plasma (4) generated by a gas discharge at atmospheric pressure (9), an electrode (3) is placed at a distance from the biological material (1). A dielectric (2) is also placed at a distance from the biological material (1) between the electrode (3) and said material (1) and an alternating high voltage is fed to the electrode (3) to ignite the gas discharge (9) that is impeded by the dielectric (2) between an active surface (5) of said dielectric (2) and the biological material (1). A solid body dielectric (2) is used as the dielectric and is positioned immediately in front of the electrode (3).
