<p>The present invention provides a device 10 for generating a non-thermal gas species 24 which may be a flow of gas plasma in the form of a gas plasma plume emitted from the device. The device comprises a gas capsule, or pressure vessel, 12 for holding a gas or gases 14 under pressure and forming a flow of gas through a reaction generator 16 to an applicator 18 when released from the capsule. Gas released from the gas capsule is energised in the reaction generator to form a gas plasma. The device is adapted to be hand-held and operated to allow it to be used for instance for cleaning and whitening teeth.</p> |
