Superior in destroying viruses and bacterias

The catalytic coating destroys viruses, bacteria, mold spores and other volatile organic compounds, as well as removes unpleasant odors. Nanoksi’s catalytic coating ensures a high level of hygiene and thus combats the spread of various viruses and diseases. Many viruses and pathogens typically also transmits from surfaces The catalytic coating is installed by spraying the substance on the surfaces, which are most commonly touched. The coating keeps, for example, door handles, handrails and other bacterial colonies more hygienic. This can have a significant impact, for example, in order to combat the current corona epidemic. The coating also ensures that future epidemics do not spread in a similar way.


In addition, the photocatalytic coating effectively and safely cleans the indoor air. It oxidizes molecules that cause unpleasant odors, causing them to be destroyed. The coating destroys allergens, food and animal odors and various air pollution. The solution also works on cigarette smoke and microbes. The cleansing is done without chemicals and is completely harmless to humans and the environment.

Healthy customers and staff

Save resources

The photocatalytic coating works around the clock, cleaning surfaces, no breaks, as long as it gets even a little light. Traditional disinfection works exactly until the substance has evaporated from the surface. One hour after disinfection, and the surface material has already started to collect microbes on its surface again, even if the room is empty, and with the airflow, the microbes travel again to the surface. Continuous disinfection of the photocatalytic coating significantly reduces the spread of infections, and customers and staff remain healthier.

The photocatalytic coating works continuously for a year after coating, saving tens of thousands of euros per year from disinfection. However, even more significant savings are made as seasonal influenza and other viral and bacterial illnesses of staff are reduced.

Viola home customer experience

The Viola Home Association Ry in Tampere, which provides services to older people, had a problem in which a norovirus epidemic spread annually among customers and staff. Although all the possible disinfectant measures were made at Viola with the hygiene nurses, the epidemic spread every year.

The Viola home was fitted with a dirt-repellent coating in the pool area and day centre washrooms, helping to maintain cleanliness, the toilets in the day centre were coated with a photocatalytic coating that destroys bacteria and viruses, as well as other harmful compounds.

Since the coating measures were taken, there has been no annual norovirus epidemic in the Viola home. The measures have led to a significant increase in both customer and personal safety, as no more pathogens grow on surfaces. The premises are also much easier to clean, the smell of urine has disappeared from the toilets, and there is no need to use such strong cleaning agents. From an economic point of view, the coating work has saved costs and the need for renovation has also been postponed further.

Labels tell you how to protect surfaces

Photocatalytic-coated surfaces can be identified from our photocatalytic coating stickers, for example, in local shops, shopping centres, cinemas, public transport, etc. you may see a sticker on the door, baskets, or in the shopping cart. This is a sign that the surfaces have been treated with a photocatalytic coating and the surfaces are self-disinfected very effectively.

How does Photocatalytic coating work?

How photo-catalytic coating works?

Photocatalytic surfaces produce reactive oxygen compounds from air oxygen and water vapour when light hits them. These compounds continue to react with organic material such as dirt, bacteria and viruses, destroying their structure. For this reason, photocatalysis is very suitable for continuous disinfection of various surfaces without chemicals. In addition to the coating, only light is required.

Photocatalytic coatings have been used for years on the exterior surfaces of buildings such as walls and windows to keep them clean from organic dirt. The functionality of these coatings indoors has been limited, as early photocatalytic materials need UV light from the sun in order to function.

Nanoksi’s sprayable new generation photocatalytic materials are well activated by visible light and do not require a direct radiation source. Indoors, even shady areas get some scattered and reflected light, which is enough to activate the coating well. As a rule of thumb, it can be said that if there is enough light so a book can be read, it is enough to keep the photocatalytic surface free of microbes.

How do we ensure that the photocatalytic coating works?

We make measurements of the hygiene situation of surfaces before and after coating. We use two different methods to measure surfaces.


ATP (adenosine triphosphate) is a high-energy compound = it stores energy. ATP is present in all living cells such as viruses, bacteria, mold, yeast and food. The ATP method is based on the activity of the enzyme luciferase: ATP + luciferase = light. Thus, ATP measurement measures a lot of ATP on any surface. The ATP meter indicates the amount in RLUs.

Hygicult TPC method

Hygicult TPC is a fast and reliable method that guarantees reproducible results with ease. The sterile plastic tube has a media-coated plastic plate on both sides with a joint to facilitate surface sampling. With the same test, a purity sample can be taken from two different objects. The sampler plate is removed from the tube and the units that formed the colony are counted from the sampler. The colony-forming units are counted on either the square centimeter or the sampler side. Pmy is a colony forming unit.
