Abstract :
Our group succeeded in developing a multi-gas plasma jet, which can generate plasma from various gas species. Using this plasma source, reactive species can be investigated in detail, since they can be generated selectively by the supplied gas species. This study aims to investigate the amount of reactive species generated by various gas plasmas, find reactive species that can inactivate bacteria and observe treated bacteria using electron microscope.
