Atmospheric pressure plasma jet in air for biological surface decontamination – JeBBioS

In this project, we propose to set up a surface biological decontamination system based on an innovative atmospheric pressure cold plasma jet technique (called plasma bullets) and to study its effect on microbiological targets for military and civilian purposes: bacilli, spores, and cocci. The first step is to conceive and to build a discharge reactor and a high voltage pulses generator that will be used for surface decontamination experiments and for characterization of plasma bullets physical and chemical properties. A parametric study will be performed in order to optimize plasma bullets biocidal effects and to highlight plasma characteristics related to these effects. Finally, we will focus on plasma/surface interaction phenomena as a function of surface and plasma bullets properties. The consortium is composed of biologists, plasma physicists, high voltage power supply specialists, and a plasma decontamination firm.
