Recently, the potential of gas plasma technology for disinfection and sterilization has been exploited. The effective inactivation of bacteria, fungi, viruses as well as toxins by gas plasma exemplifies the broad application of this technology. However, information concerning the effect of gas plasma on microorganisms and their biomolecules, as well its mechanism of action, remain somewhat limited. Here, we focus on the inactivation of viruses by gas plasma, for which very few studies have been reported in the literature. This chapter will introduce our recent investigation of N2 gas plasma, produced by applying a short high-voltage pulse using a static induction (SI) thyristor power supply, which inactivates influenza virus. The biological significance of changes to the virus induced by gas plasma treatment will also be discussed read more ...
