Abstract
A method of disinfecting a surface that is contaminated with a virus or suspected of contamination with a virus, including: producing a reactive gas by forming a high-voltage cold plasma (HVCP) from a working gas with a dielectric barrier discharge (DBD) system at a voltage of 20 kV to 150 kV; transporting the reactive gas at least 1 meter away from the HVCP; followed by contacting the surface with the reactive gas.
Claims20
A method of disinfecting a surface suspected of contamination with a virus, comprising:
- producing a reactive gas by forming a high-voltage cold plasma (HVCP) from a working gas with a dielectric baffler discharge (DBD) system;
- transporting the reactive gas at least 1 meter away from the HVCP;
- followed by
- contacting the surface with the reactive gas to disinfect the surface,
- wherein a host infected with the virus had contacted the surface,
- the reactive gas comprises (a) optionally ozone, and (b) at least one reactive or excited species other than ozone, and
- effectiveness of the reactive gas at disinfecting is greater than that of the ozone content alone.
A method of disinfecting a surface contaminated with a virus, comprising:
- producing a reactive gas by forming a high-voltage cold plasma (HVCP) from a working gas with a DBD system;
- transporting the reactive gas at least 1 meter away from the HVCP;
- followed by contacting the surface with the reactive gas to disinfect the surface,
- wherein a host infected with the virus had contacted the surface,
- the reactive gas comprises (a) optionally ozone, and (b) at least one reactive or excited species other than ozone, and
- effectiveness of the reactive gas at disinfecting is greater than that of the ozone content alone.
A method of disinfecting a surface contaminated with a virus, comprising:
- (I) producing a reactive gas by forming a high-voltage cold plasma (HVCP) from a working gas with a DBD system;
- (II) transporting the reactive gas at least 1 meter away from the HVCP;
- (III) followed by contacting the surface with the reactive gas to disinfect the surface,
- (IV) obtaining a virus sample from the surface after the contacting, and
- (V) determining an amount of remaining virus after exposure to the reactive gas,
- wherein, if the surface is not disinfected by the contacting, repeating (I), (II) and (III) until the surface is disinfected,
- the reactive gas comprises (a) optionally ozone, and (b) at least one reactive or excited species other than ozone, and
- effectiveness of the reactive gas at disinfesting is Greater than that of the ozone content alone.
