Abstract

A kind of nonequilibrium air plasma based on surface microdischarge is developed, behaving as per editing aspect. Please confirm the change. as large homogeneous scalable discharge area. Its inactivation effect on Bacillus cereus is investigated and 5.3-log reduction in cell viability is achieved within 150-s exposure. The pH value, hydroxyl (OH), and nitric oxide (NO) concentration in the extracellular solution after plasma treatments are detected. In addition, a transmission electron microscope is utilized to observe the cell damage from the morphology. Some potential chemical and biomedical processes involved are discussed. It is considered that the oxidation effect of reactive oxygen species plays a crucial role, and the nitration effect as well as the synergistic effect in the acid milieu, jointly contribute to the NAP-induced bactericidal process. 0018-9456
