Inactivation of multidrug-resistant pathogens and Yersinia enterocolitica with cold atmospheric-pressure plasma on stainless-steel surfaces

Cold atmospheric-pressure plasma (CAP) is a new, non-thermal decontamination method. Plasma is the fourth state of matter and includes many different bactericidal species including NO, NO2, N2O, CO, CO2, H2O2 and ozone [1,2]. Plasma is generated by applying an electric field to a working gas, in this study to inexpensive ambient air. The generated plasma species cause oxidative stress and damage bacterial cells [3]. If the amount of reactive species exceeds the capacity of cellular repair mechanisms, cell death occurs.
