Plasma needle is a radio-frequency driven atmospheric plasma, generated in a helium-air mixture at the tip of a pointed metal pin. Plasma needle is a non-equilibrium plasma, characterized by a moderate chemical activity. The discharge is small-sized; it consumes little electric 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 we characterize the needle discharge: the measurements of electric voltage and power, temperature, radiation and radical fluxes are shown. Furthermore, its applications in treatment of biological samples are discussed.
