  • Patent number: 9662412
    Abstract: Exemplary apparatuses and methods of killing or deactivating bacteria are disclosed herein. An exemplary apparatus for killing or deactivating bacteria includes a plasma vapor chamber. The plasma vapor chamber has a vapor inlet for allowing a vapor into the chamber, a high voltage electrode, one or more grounding electrodes. The one or more grounding electrodes at least partially surrounding the plasma vapor chamber. The plasma vapor chamber includes an outlet for allowing fluid to flow out of the chamber. When the chamber is filled with vapor for a period of time sufficient to saturate the chamber with vapor, the high voltage electrode is energized to generate plasma throughout the chamber.

  • Patent number: 9550007
    Abstract: Exemplary methods and systems for killing or deactivating spores include applying a fluid to a surface containing a spore; and applying direct or indirect plasma to the surface for a period of time. In some embodiments, the fluid includes water. In some embodiments, the spore is Clostridium difficile and in some is Bacillus Anthracis. In some embodiments, the fluid is in the form of a vapor, a fog, a spray, a mist or an aerosol, which may be activated prior to or after applying the fluid to a surface. In some embodiments, peroxynitrite is created in the fluid during the method. Another exemplary embodiment of killing or deactivating a spore includes treating spores with direct plasma or indirect plasma for a period of time and applying an antimicrobial to the spores. In some embodiments, the antimicrobial is an alcohol, a bleach or an alcohol-based sanitizer.

  • Publication number: 20150157870
    Abstract: Exemplary embodiments of shape conforming dielectric barrier discharge (DBD) plasma generators are disclosed herein. One exemplary embodiment includes a flexible pad and a plurality of electrodes located in the pad within close proximity of each other, and a flexible dielectric barrier surrounding the plurality of electrodes and separating the plurality of electrodes from each other. Wherein when a high voltage pulse is applied to one or more of the plurality of electrodes, plasma is produced between a surface of the flexible pad and a portion of the body in close proximity to the flexible pad.

  • Publication number: 20140322096
    Abstract: A sanitization station including a fluid source and one or more plasma generators for generating non-thermal plasma is disclosed. One or more nozzles spray a mist or stream of fluid through plasma generated by the one or more plasma generators to activate the fluid. The fluid is then used to sterilize an object. Another sanitization station includes a chamber for holding a fluid and a plasma generator in fluid communication with the chamber for generating plasma. A circulating source moves the fluid in the chamber past plasma generated by the plasma generator to activate the fluid and one or more spray nozzles coat the surface of an object with fluid that is activated by plasma.
