Re-infection in hospitals after operations is a huge problem – especially for weak and older patients. 30 % savings are expected if it is possible to avoid re-infections. Efficient scalable solutions are needed. A number of demonstrators based on three different types of antibacterial/self-cleaning surface strategies will be tested:
- Electroplating a two component metal system providing a large electrochemical potential difference creating small “surface batteries” that will kill bacteria caused by anode and cathode reactions.
- Releasing of antibacterial materials like copper and/or silver ions from zeolites integrated in organic coatings, or by immobilizing an antibacterial agent such as enzymes, anti-fungicide, Cu ions, etc. in pores formed by anodizing aluminium.
- Use of doped TiO2 catalysing the generation of radicals sterilizing the surface upon UV light exposure.
