Infectious diseases can be transmitted to humans, or between humans and animals, by airborne viruses and bacteria, known as infectious aerosols. Current protective measures that individuals can take to avoid inhaling such aerosols are either marginally effective (personal face masks) or impractical (self-contained breathing apparatuses). Building ventilation systems employing high-efficiency filters to prevent distribution of such aerosols suffer from high energy costs and high filter replacement costs. The development of conventional, intramuscularly administered vaccines takes months or years to produce enough doses to protect a population from a rapidly spreading infectious disease. Airborne viruses and bacteria have been shown to be completely inactivated when exposed to non-thermal plasmas. Results indicate the potential for sub-lethal exposures of airborne pathogens could render them unable to spark an infection in a host, but still retain the necessary surface proteins to cause an immune response in the host.

A method for generating atmospheric pressure cold plasma inside a hand-held unit discharges cold plasma with simultaneously different rf wavelengths and their harmonies. The unit includes an rf tuning network that is powered by a low-voltage power supply connected to a series of high-voltage coils and capacitors. The rf energy signal is transferred to a primary containment chamber and dispersed through an electrode plate network of various sizes and thicknesses to create multiple frequencies. Helium gas is introduced into the first primary containment chamber, where electron separation is initiated. The energized gas flows into a secondary magnetic compression chamber, where a balanced frequency network grid with capacitance creates the final electron separation, which is inverted magnetically and exits through an orifice with a nozzle. The cold plasma thus generated has been shown to be capable of accelerating a healing process in flesh wounds on animal laboratory specimens.

A cold plasma accessory having a hand piece having within in it flexible tubing, wiring, a PCB board connected to the wiring, and a conductive connector tube electrically connected to the PCB board, the conductive connector tube having an inner channel, a rigid tube extending from the distal end of the hand piece, and an electrode within the rigid tube. The electrode comprises a conductive connector having a contact surface contacting the conductive connector tube, a distal end surface facing away from the conductive connector tube, and a channel extending through a center of the conductive connector, the channel being fluidly connected to the flexible tubing, the distal end surface of the conductive connector being outside of the channel in the conductive connector, and a conductive wire connected to the distal end surface of the conductive connector.

An array of non-thermal plasma emitters is controlled to emit plasma based on application of an electric current at desired frequencies and a controlled power level. A power supply for an array controller includes a transformer that operates at the resonant frequency of the combined capacitance of the array and the cable connecting the array to the power supply. The power into the array is monitored by the controller and can be adjusted by the user. The controller monitors reflected power characteristics, such as harmonics of the alternating current, to determine initiation voltage of the plasma and/or resonant frequency plasma emitters. The array of non-thermal plasma emitters may be used in therapeutic, diagnostic, and/or medical sanitization applications, including where a non-thermal plasma treatment regimen is prescribed.
