Abstract

A cold atmospheric pressure gliding arc plasma jet has
been developed and applied to disinfection. The size of the plasma output is
about 6 mm in diameter and 10 mm in length. Ar gas at a flow rate of 10 slm
and 25 W plasma power are used. Plasma discharge is produced between the
divergent electrodes and the jet appears as an effluence of the gas flow.
When a \textnormal{pseudomonas} culture is placed at 8 mm below the
torch for 1minute, where the gas is at room temperature, the
bacteria within a 16 mm diameter circle are almost completely killed. As the
UV radiation is well below the safety regulation, the bacteria are
inactivated by the total effect of UV radiation and others like the reactive
species and the charged particles.
