Led by academic Imre Dékány, the staff of the Department of Materials Science at the University of Szeged (SZTE) uses the results of decades of research, together with a Hungarian company. A procedure has been developed to render the microbes permanently unviable on the treated surface, be they bacteria, fungi or viruses. With this coating, any surface can be treated, from upholstery to metal, plastic and rubber to glass. Thereafter, for up to a year, fungi, bacteria and viruses, including the new type of coronavirus, will not be able to adhere.
The importance of surface protection
The coating contains only natural active ingredients, is colorless and odorless, is incorporated into the treated surface at the molecular level, and can provide protection under natural or artificial light for up to one year without being removed. These substances are found in many other products, from toothpastes to medicines to gum.
Protecting the surface is also very important because the most common infections, including the Covid-19 SARS-CoV-2 virus, can be collected by touch in places where many people turn and touch different objects (public transport, public spaces). , Hospitals, universities, offices, restaurants, etc.) Therefore, this technology is based on the special coating to spray different surfaces. The special coating contains titanium dioxide, which reacts with light and has a hygienic effect.
Laboratory tests prove efficacy
This procedure called Resysten has been on the market for years, but now virological studies have also confirmed its effectiveness, which until now has not been officially documented in this way.
The experiments examined viral survival at two temperatures (room temperature and 4 ° C) by taking samples at two different time points and using dark controls in both cases. The first time was the aerosol / drop drying time and the second was 10 minutes after drying. Both the photoreactive and control plates were illuminated throughout the experiment, except for the dark controls. Professor Boldogkő informed Origo that the following findings had been made during the tests:
1. In the case of the dry point reaction, a decrease of almost four orders of magnitude (ten thousand times) was observed in the virus on the photoreactive plate compared to the control plate.
2. After drying, the virus completely disappeared from the photoreactive plate. More specifically, no infectious virus particles remained on the photoreactive plaque.
3. At four (4) ° C, the number of infectious viruses on the photoreactive plate was reduced by approximately three orders of magnitude before drying.
4. At four (4) ° C, after drying, the difference between treated and untreated surfaces decreased.
5. Without illumination, there was no significant difference between photoreactive and control surfaces, with only a small reduction in virus measured on plaque treated at only 4 ° C.
Based on all this, it can now be affirmed on a scientific basis that this procedure can play an important role in the superficial control of fungi, bacteria and viruses, including Covid-19, while maintaining existing disinfection and cleaning protocols. That is, it can be applied in the “first line” of defense, in addition to the mask, complementing its use.
The procedure has already been tested in practice.
ResYST Hungary Kft., Which distributes the product, has serious references from practical life, including the hospital area, which show that this procedure can be used extremely effectively against bacterial infections.
For example, the Kisvárda hospital has a comprehensive set of annual data showing that the number of nosocomial infections in the hospital has drastically and permanently decreased after the application of this surface treatment. At the Markhot Ferenc Hospital in Eger, a complete superficial treatment was carried out last year, within the framework of a 3-year cooperation, so the data series is shorter, but the results are similar.
It is interesting, but important, that this hygienic coating, developed, manufactured and marketed entirely in Hungary, cannot be considered a disinfectant according to the EU biocide regulations, because it does not contain a biocidal component (i.e. poison). However, in Hungary, the National Center for Public Health already issued a document in March 2020 in which it claimed that it had a similar but permanent and long-lasting effect to biocides, but that it could not yet be called a disinfectant under EU law.
However, the procedure radically transforms the world of infection control, epidemic control.
ResYST Hungary Kft. Assumes a one year warranty for one treatment, because in their experience the coating capacity does not decrease at all during that period.
Mechanism of action of the special coating.
In the presence of light, by decomposing the humidity of the air, due to the catalytic effect of titanium dioxide, the so-called formation of free radicals is activated and it also works continuously, permanently. The compound is incorporated at the molecular level into the support surface, whether it is solid, and can only be removed by physical abrasion, that is, a negligible amount is released into the environment (approximately as much from a surface of continuous use such as copper, for example, during a long process of polishing a copper handle).
The essence of the free radical process is that the material helps the surface to behave in the same way that noble metals (silver, copper) behave by themselves, that is, to excite external light it pushes its electron orbit an level higher than water.
These molecules then aggressively break down organic matter and volatile organic compounds.
One of the most important elements of the Hungarian development is that the internationally known reaction, which was already patented in Japan in the 1970s, is not capable of producing ultraviolet light, but with the light value of a 40-watt bulb in the longer term.
The environmental impact is minimal
In relation to this process, it is also important to know that conventional disinfectants are simple poisons that destroy proteins and are then absorbed, drained or released into the air by evaporation in the form of gases. Therefore, its effect is instantaneous, after disinfection the surface remains hygienic until new pathogens appear on the site (that is, for a very short time).
Therefore, disinfection should be done as often as possible to achieve the effect. This places a serious and continuous burden on the environment due to toxic gases released into the air and chemical residues entering the water and soil, while the efficiency of the process is low. However, the ResYST process does not release toxic substances into the environment.
Titanium dioxide is also one of the most common food additives like e171 and is widely used by the chemical industry as a bleach, found in all toothpastes, Tic-Tac candies, gum, and paints. From this special coating, an amount of candy that is orders of magnitude less than the content of titanium dioxide leaves the environment as a one-square-meter macromolecule.
