Inactivation efficacy of atmospheric air plasma and airborne acoustic ultrasound against bacterial biofilms

Abstract Biofilms are complex microbial communities that present serious contamination risks to our environment and health. In this study, atmospheric air plasma and airborne acoustic ultrasound technology were applied to inactivate Escherichia coli and Listeria innocua biofilms. Both technologies w...
