Abstract

Rapid, safe and effective sterilization of harmful microorganisms is important for the public in general and hospital patients in particular. Non-equilibrium gaseous discharges have been found to be effective agents for sterilization. The ability to generate these discharges at atmospheric pressure makes the sterilization process practical and inexpensive. Cold plasmas generated by such discharges make their use suitable for applications where medium preservation is desired. In addition, these cold plasmas proved to be very effective due to the synergistic effects of active species, charged particles and UV photons which interact with the cells of microorganisms on the atomic and molecular levels. In this study, a high voltage pulsed plasma sterilization method, a simple and efficient way, was tried on the Staphylococcus aureus.
