      There is a growing body of literature that recognizes the importance of plasma treated water (PTW) for inactivation of microorganism. However, very little attention has been paid to the role of reactive nitrogen species (RNS) in deactivation of bacteria. The aim of this study is to explore the role of RNS in bacterial killing, and to develop a plasma system with increased sterilization efficiency. To increase the concentration of reactive oxygen and nitrogen species (RONS) in solution, we have used vapor systems (DI water/HNO 3 at different wt%) combined with plasma using N 2 as working gas. The results show that the addition of the vapor system yields higher RONS contents. Furthermore, PTW produced by N 2  + 0.5 wt% HNO 3 vapor comprises a large amount of both RNS and ROS, while PTW created by N 2  + H 2 O vapor consists of a large amount of ROS, but much less RNS. Interestingly, we observed more deactivation of E. Coli with PTW created by N 2  + 0.5 wt% HNO 3 vapor plasma as compared to PTW generated by the other plasma systems. This work provides new insight into the role of RNS along with ROS for deactivation of bacteria.
