The hairline plasma jet (hairlINePlasma) is a cold atmospheric pressure plasma source mainly for biological and medical applications. hairlINePlasma uses the physical effect of negative dc corona discharges and produces a nanosecond self-pulsed microplasma with a very thin plasma filament. The Plasma filament has a diameter of about 30 µm and a length of up to 3 cm. Due to this geometrical features, hairlINePlasma is particularly suitable for the treatment of microscopic cavities and the localized functionalization of conductive surfaces.

The Miniaturized Noble Gas Plasma Jet has originally been designed to be inserted into the working channel of a conventional endoscope. It has a tube-like character, is flexible, very thin and generates a biologically active jet plasma at the gas outlet. The device consists of an inner plastic tube, a ceramic nozzle, an outer plastic tube and a metal wire. The inner plastic tube is plugged upon the thin end of the ceramic nozzle.
