A) The killing activity of discharged gas to bacteria in 1-day old S. aureus biofilms as measured using the MTT assay. Insert: images of MTT stained bacteria in biofilms grown on 6-well plates before (left) and after (right) discharge argon treatment. B) Confocol microscope images of live and dead bacteria in biofilms before (left) and after (right) treatment with discharge argon. Experimental conditions: power: 100W; exposure time: 5 min ; gas flow rate: 2.4 ft3 h−1 . Data represent the mean and SD of at least three samples.
