Summary form only given. In the recent days, since the epidemic spread of diseases, sterilization has become very important. Atmospheric pressure plasma jets which are used locally and effective results for sterilization procedures are popular. In this study, we produced atmospheric pressure plasma jet with helium flow and used for sterilization of Escherichia coli and Staphylococcus aureus. In the experiments, hundred-fold diluted 250 μlt McFarland bacteria were used in eppendorf tubes for plasma treatment. The effects of plasma treatment time (1, 2, 3 second), applied voltage frequency (5-10 kHz) and amplitude (Vpp 15-16 kV) on sterilization were investigated. Plasma current-voltage characteristics and optical emission results were given.
