Description

He/N<small>2</small> cold atmospheric plasma treatment of E. coli suspension leads to a fast and efficient inactivation process. Significant generation of ammonium is reported. The formation of NH<small>4</small><small>+</small> species in saline solution treated by cold atmospheric plasma is proposed for the first time as the main process responsible for the fast bacterial inactivation in pH-buffered solutions, at ambient temperature and physiological pH.
