Abstract

Effective biofilm inactivation using a handheld, mobile plasma jet powered by a 12V dc battery and operated in open air without any external gas supply is reported. This cold, room-temperature plasma is produced in self-repetitive nanosecond discharges with current pulses of ∼ 100ns duration, current peak amplitude of ∼6mA and repetition rate of ∼20kHz. It is shown that the reactive plasma species penetrate to the bottom layer of a 25.5μm-thick Enterococcus faecalis biofilm and produce a strong bactericidal effect. This is the thickest reported biofilm inactivated using room-temperature air plasmas.
