Formation of Reactive Chlorine Species (RCS) in Plasma Activated Medium (PAM) for Bacterial Sterilization

Normal saline solution offers much better living environment for most bacteria than deionized water [1] . However, the plasma activated normal saline is proven to have much stronger bactericidal effect than the plasma-activated deionized water [2] . The bactericidal effect of these plasma activated media (PAM) could be caused by the dissolved reactive oxygen and nitrogen species (RONS) [3] . This knowledge breach is a serious area in plasma science which significantly hinder the future design and development of plasma sources for their proposed applications.
