Abstract A helium cold atmospheric pressure plasma jet (HCAPPJ) driven by a commercial neon power supply was designed and utilized for inactivation bacteria. The generated reactive spices HCAPPJ were investigated optical emission spectroscopy. species of OH, OI, N 2 1+ , He identified in the UV–Vis wavelength region. not detected between 200 nm 300 nm, as flow rate gas increased that led to temperature reducing value near room temperature. In this work, we studied impact on Gram-positive Gram-negative survival amounts two types bacteria decreased vastly when equal 10 L/min.
