What do we understand by disinfection?
Disinfection is intended to prevent infections and is a hygiene measure. For this purpose, pathogens on dead or living material are inactivated. This means the number of pathogens is greatly reduced. Consequently, an infection is no longer likely.
What are the characteristics of chemical and physical methods of disinfection?
First of all, microbicidal substances contaminate surfaces and the human skin. In addition, by-products and odors can be produced. Furthermore, chemical methods pollute the environment. In addition, microorganisms can build up resistance to disinfectants.
Physical methods such as thermal disinfection or disinfection by UV rays are above all more compatible for the environment. In addition, they do not leave behind any undesired by-products or odors (ozone generated by UV-C radiation is odor-tainting and toxic). However, UV-C radiation is harmful to human health. Therefore they are not suitable for all applications.
Physical methods based on UV-C light cannot be implemented in every application due to lack of scalability. Therefore they are mainly used in laboratory environments. Chemical methods, on the other hand, can be scaled as desired, but are resource intensive and cause problems.
Is there a method for hygienic disinfection that is neither dangerous for the environment nor for people?
Yes, plasma-based disinfectors (Plasma-Bod) allow disinfection free of chemicals.
The killing of pathogens is achieved by a precisely adjustable quantity of short-time stable, high-energy micro- and nanoparticles.
Therefore the disadvantages of chemical methods are eliminated. These include environmental pollution, unwanted by-products (DNP) or odors. Furthermore, no resistances can be developed by microorganisms.
In contrast to the disinfection with UV-C light, the P-Bod principle has no problems with shading. Consequently, it can also be used on uneven and amorphous surfaces.
Furthermore, P-Bod can also be used for the disinfection of human skin. Due to the arbitrary scalability of the principle, applications such as hygienic hand disinfection are conceivable. Only a power source and ambient air are necessary. For this reason, the technology can be universally implemented in the most diverse devices and performance classes for disinfection. The solutions for disinfecting surfaces can also be very small. Even small, portable applications with rechargeable batteries are possible.
