Disinfection method using a disinfection agent formed in situ by reaction of H.SUB.2.O.SUB.2 .and NO.SUB.2.-
The invention relates to a disinfection process comprising the feed materials H.sub.2O.sub.2 and NO.sub.2.sup.− and a mixing step and a distribution step, wherein the mixing step and the distribution step (during which each point on the surface being disinfected is wetted with a solution of active substance) are implemented during a processing period Z.sub.A. An exposure step follows, in which the distributed solution of active substance acts upon the surface in contact with the solution of active substance during an exposure period Z.sub.E. In this process, the maximum NO.sub.2.sup.− concentration during the mixing step is of 300 mM, and the time-integrated reaction rate W is represented during the exposure period Z.sub.E by the integral formula (I), where k.sub.1 denotes the pH-value-dependent speed constant of the reaction between H.sub.2O.sub.2 and NO.sub.2.sup.− and the pH value of the solution of active substance before it contacts the surface being disinfected lies in the range of 2.1≤pH≤6.8. The invention also relates to a device for providing the solution of active substance.
Production of immune-response-stimulating aerosols by non-thermal plasma treatment of airborne pathogens
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.
