Cold Plasma Technologies & Applications

The Cold Plasmas otherwise called the non-thermal plasmas is an emerging branch of plasma science utilizing the effectiveness of ionized gases produced by the resistive barrier plasma discharge on sterilizing bacteria has been analyzed. Bacteria at a dilution that achieved a countable number of colonies were exposed or not exposed to ionized gases for various periods of time and monitored to determine the effects of ionized gas treatment. The results of these experiments indicate that effective decontamination can be achieved within minutes when bacteria are exposed to ionized gases in close contact to the contaminating surface. On the battlefield or in remote locations, ionized gases could be used to decontaminate potentially harmful agents of bacterial origin. In hospitals on the battlefield and/or in remote locations, ionized gasses could be used to sterilize surgical equipment, decontaminate potentially infected areas in post-operative care units following surgery. In such cases the self-generated gas flow from the reactor facilitates the application of the ionized gases over the large infected areas.
