By definition, the nonthermal plasma (NTP) is partially ionized gas where the energy is stored mostly in the free
electrons and the overall temperature remains low. NTP is widely used for many years in various applications
such as low-temperature plasma chemistry, removal of gaseous pollutants, in gas-discharge lamps or surface
modification. However, during the last ten years, NTP usage expanded to new biological areas of application
like plasma microorganisms' inactivation, ready-to-eat food preparation, biofilm degradation or in healthcare,
where it seems to be important for the treatment of cancer cells and in the initiation of apoptosis, prion inactivation, prevention of nosocomial infections or in the therapy of infected wounds. These areas are presented and
documented in this paper as a review of representative publications.
