What is the disadvantage of photocatalysis?​
Nothing. As a natural phenomenon, photocatalytic reactions occur all the time. We just make it more efficient. The chemicals and structures used in the coating comply with the EU’s REACH regulations.​


Does the treatment leave marks to the surface?​
No. The surface treatment is nano-grade in thickness, it is so thin that it cannot be seen.​


Are there any temperature restrictions on the coating in terms of temperatures?​
Yes, but they are very high. Let’s talk about hundreds of degrees where the metal and plastic below melt sooner. You can go so far in the frost that it doesn’t matter in practice.​


How new is this photocatalysis phenomenon? How much has it been studied?​
Photocatalysis is a well-known phenomenon, it is more than 100 years old. As an antimicrobial effect, it has been studied for decades. There are a great many certified studies. The photocatalytic coating provides a very significant antimicrobial effect.​


Is the coated surface harmful on skin contact or if ingested orally?​
No. The coating is thin and substance doesn’t spread from the surface. The coating is applied in our factory by our experts.​


Does the photocatalytic coating protect us from infectious diseases?​
Not alone. It helps to keep protected sites free of pathogens and can stop the flow of viruses at the site but does not replace the authority’s instructions, for example when protecting against the Corona virus. The manufacturer has good experiences, e.g., on the protection of old people’s homes against the harmful Norovirus.


Can the efficiency of photocatalysis be measured?​
Yes. The functionality of the Fotonit photocatalytic coating is tested with various other methods measuring surface hygiene. The ATP measurement is the one we use the most. ATP (Adenosine triphosphate) is a cellular metabolite. The ATP measurement describes the amount of organic dirt on a surface. The measurement is based on the ATP–luciferase reaction which produces light. The meter reports the amount in relative light units (RLU). The lower the number, the less organic the dirt that acts as a breeding ground for microbes and viruses exists on the surface.​


How do different microbes like viruses and bacteria differ in their removability?​
Viruses are eliminated more easily than bacteria. Bacteria tend to form so-called biofilms that are much more difficult to destroy than individual viruses from the surface. The most challenging are long-standing viruses and bacteria, such as norovirus and Salmonella. The photon coating also works effectively on them.​


Does the Fotonit coating affect the indoor air?​
Yes. Light catalysis also purifies the air. This is also sensory – the air feels fresher. (When it is especially desired to clean the indoor air, the walls and ceiling in the room, for example in senior houses, are coated).​


Has it been tested for the Corona virus?​
So far, there are certified studies from Germany where coronavirus has been studied in relatives. The mechanism itself for oxidizing compounds is that it attacks the so-called hydrocarbon bond present in organic materials. The mechanism is very generic and does not actually see which virus, bacteria, mould or even a large carbon molecule is involved. Oxidizing compounds similarly oxidize them to oxygen and water. A very direct conclusion is that if the mechanism works in this way with all viruses and bacteria that have been tested and measured so far, then it will also work with the SARS-CoV-2 (Covid-19) virus. In the world, the destruction of the SARS-CoV-2 (Covid-19) virus is challenging to test because only a few research entities are allowed to process the viral material. And the development of vaccines is now more important given viral variants.


When wiping the Hublet Tablet with cleaning fluids, does that harm the Fotonit Photocatalytic Coating?
No, it does not. Tablets can be cleaned using normal cleaning products. ​
