The Potential Use of a Cold Atmospheric Plasma Jet for Decontamination of Hospital Surfaces. A Pilot Study

Hospital surfaces are a source of potential infection due to contamination by microorganisms such as bacteria and viruses. Bacterial biofilms particular importance, their persistence in the hospital environment. Cold atmospheric pressure plasma (CAPP) is novel method surface decontamination. In this study, we aimed show use CAPP jet for were grown on common materials treated with an air-driven jet. Viable measured. Confocal microscopy staining used gather images CAPP-treated biofilms. The effect inactivation was also assessed alongside detergent. inactivated clinically relevant both planktonic biofilm structures.
