Atmospheric-pressure dielectric barrier discharge (DBD) in air
- A pulsed atmospheric-pressure dielectric barrier discharge (DBD) device operating in air is investigated for medical applications such as for skin disinfection and promotion of wound healing. The device ignites plasma on objects of high capacitance such as the human body and with grounded electrodes. Plasma parameters such as electron density and electron distribution function are determined. Plasma chemical kinetics is simulated and the production of biologically-useful molecules namely nitric oxide (NO) and ozone is estimated for use in dermatology. Prior to plasma characterisation on human body, simple materials such as aluminium (flat and spike), buffer solution (PBS) and glass are used as grounded electrodes for plasma characterisation. A single-filamentary discharge with spike, a stochastic-filamentary discharge with aluminium and PBS, and a homogeneous discharge with glass are observed. 2 minute DBD treatment of mouse skin shows no inflammation or any carcinogenic effects.
