Fotonit® – Surfaces protected by light

Every day we visit spaces where surfaces have been touched by thousands of hands before us. On these surfaces, live and thrive millions of pathogenic viruses, bacteria, yeasts and moulds. 

Today’s scientific research increases understanding and transparency about why we get sick and why diseases spread. The rapid spread of infectious viruses and bacteria through contact surfaces has contributed significantly to global health problems. Epidemics have made us understand the importance of good surface hygiene as part of the fight against infectious diseases.

Scientific research also offers ways to fight against these invisible pathogens. We support healthcare and provide high-tech solutions to improve surface hygiene. That’s why we developed a coating solution that self-disinfects with the power of light, FOTONIT® photocatalysis coating, with which we make spaces and contact surfaces safer for people.

Self-disinfecting surfaces promote health and well-being and the principles of sustainable development, as they provide cleaner contact surfaces without chemicals, utilizing technology instead of toxins.

FOTONIT® photocatalysis coating based on nanotechnology kills more than 98 percent of common and familiar bacteria and viruses, such as corona and noroviruses, coli, listeria, and salmonella bacteria.

Fotonit® Benefits

Hygiene no longer depends on manual work or work efficiency. Reducing illnesses and a clean environment improves a person’s quality of life and increases well-being. Find out about the operating principle of photocatalytic coating at the end of the page.

  • Ensures good surface hygiene to fight against infectious diseases.
  • Minimises risks as flu and other infectious diseases begin to spread again, when people return to work and hobbies.
  • Safe spaces and clean surfaces increase the company and employer image.
  • Reducing illnesses increases staff productivity and reduces medical costs.
  • Reducing the need for heavy cleaning and strong chemicals translates into savings on cleaning costs.

Fotonit® Applications

The Fotonit® photocatalytic coating is suitable for all spaces with a high number of daily visitors. The coating makes the spaces and surfaces safer for people.

  • Swimming pools, gyms and skating rinks
  • Shops, shopping centres and restaurants
  • Museums, theatres, cinemas and libraries
  • Concert halls and event centres
  • Hotels, ski resorts and spas
  • Vehicles and car rental shops

  • Offices and agencies


Our Fotonit® photocatalytic coating method involves spraying all interior surfaces with the coating. As an indication of its high degree of Finnish origin, our service has been awarded the Finnish Key Flag symbol.

  • Activates within 24 hours of application 
  • Invisible, flexible and porous protective coating
  • Suitable for all types of  surface materials
  • Annual re-application recommended
  • Improves indoor air quality

Our customers speak for us

We make the world a safer place one surface at a time. Over the years, we have applied thousands of coatings all over Finland to homes, commercial premises, shops, shopping centres and amusement parks, as well as to public spaces such as schools, assisted living facilities and hospitals. Read more about why our customers chose Nanoksi Fotonit® photocatalytic coating.

This is how photocatalysis works

  1. The coating is activated by light and airborne water vapour.
  2. The activated coating forms reactive oxygen compounds.
  3. Oxygen compounds are very short-lived, as they react with microbes and VOCs on the surface.
  4. The microbes and volatile organic compounds (VOCs) decompose while oxygen compounds are converted to water and carbon dioxide.

Proven to work

The Fotonit® photocatalytic coating has been proven to work by a study conducted at the University of Tampere. The photocatalysis is capable of destroying 98% of influenza viruses, among other things, in two hours under normal room light.

Want to know more? Ask for the research results

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.
