Plasma needle is a radio-frequency driven atm. plasma, generated in a helium-air mixt. at the tip of a pointed metal pin. Plasma needle is a nonequil. plasma, characterized by a moderate chem. activity. The discharge is small-sized; it consumes little elec. power, and it does not cause thermal damage to the surrounding objects. These features make it suitable for local, high-precision surface modification and treatment of living cells and tissues. In this work the authors characterize the needle discharge: the measurements of elec. voltage and power, temp., radiation and radical fluxes are shown. Furthermore, its applications in treatment of biol. samples are discussed.
