Proof of effectiveness in field testing

The Dyphox® coatings were tested for the first time in a large-scale field study in two hospitals in Regensburg, Germany. As part of the study, various surfaces were treated either with an active antimicrobial coating or a control coating. Over several months, the number of bacteria on the active and control surfaces was determined and compared. Meanwhile, everyday clinical operations continued, and routine cleaning and disinfection of the surfaces were carried out unchanged according to the hygiene plan.

Ultimately, the evaluation provided a clear result. The Dyphox coatings were able to reduce the risk of high germ contamination on surfaces by up to 67%. The results of this field study were recently published in the internationally renowned Journal of Hospital Infection.

Airbus Bizlab Accelerator Programme

Out of 704 applicants worldwide, Dyphox® was selected as one of 6 start-ups for Airbus Bizlab Acceleration Programme Season #5 in Hamburg. Now in its fifth year, Airbus offers start-ups the opportunity to transform innovative technologies into valuable business models with this 6-month programme. We have been on this exciting journey since October 2019. Thanks to a wide range of offers and support from Airbus, we are able to test Dyphox® coatings in aircraft cabins in terms of sustainability, customer demand and technical feasibility, and develop initial business models.

Dyphox® was founded in 2010 as a spin-off of the University Hospital Regensburg. Ten years of research and development work made it possible for us to optimally develop the products. We have now succeeded in bringing highly effective surface coating and additive products to the market using state-of-the-art technology.

DYPHOX Universal, the antimicrobial retrofit coating

Dyphox® Universal now provides an effective and safe hygiene solution for high-touch surfaces in both professional hospital hygiene and public areas. The Dyphox® Universal coating is also recommended for the antimicrobial treatment of production facilities and offices. The colourless Universal coating, which can be wiped on retroactively, permanently closes hygiene gaps to optimally protect patients, employees and customers. The unique operating principle ensures consistent effectiveness on dry and moist surfaces. This makes Dyphox® Universal the only antimicrobial surface coating proven to work under real-world conditions.

Which materials are suitable?

Melamine/laminate, ABS and rigid/soft PVC plastics are used in many office furnishings and are ideal for coating with the Dyphox® Universal retrofit coating.


Aluminium is well suited for coating with the Dyphox® Universal retrofit coating.


Stainless steel is outstandingly well suited for coating with the Dyphox® Universal retrofit coating. High-touch objects such as door handles can thus be provided with an antimicrobial effect.

Die DYPHOX Technologie: Photodynamik

Dyphox® coatings contain a special photocatalyst.

Visible light excites the photocatalyst and transfers energy to the surrounding oxygen. Singlet oxygen is produced which kills germs efficiently.

The surface is disinfected. As a result, Dyphox® permanently closes hygiene gaps.
