Verification of the sterilization effect of atmospheric pressure plasma on bacteria attached to smartphones.
We conducted an experiment aimed at visualizing the extent of the sterilization effect of atmospheric pressure plasma irradiation and clarifying its effectiveness and challenges!
We examined the sterilization effect of atmospheric pressure plasma on microorganisms attached to the glass surface of smartphones and will introduce the details of the microorganisms involved and the results. Microorganisms were collected from the "untreated area" and the "area irradiated with atmospheric pressure plasma" on the glass surfaces of two staff members' smartphones using cotton swabs, and cultured. We then evaluated the sterilization effect by comparing the colonies of microorganisms formed on the Petri dishes from both areas. As a result, mainly "bacteria from hands" and "bacteria from the environment" were identified, with at least three types of microorganisms observed. On the plates after plasma irradiation, the number of bacterial or yeast colonies decreased compared to the "untreated" ones. Fungi and actinobacteria were still observed after plasma irradiation. [Observed Microorganisms] ■ Bacteria or Yeast ■ Filamentous Fungi (Mold) ■ Actinobacteria *For more details, please refer to the related links or feel free to contact us.
