Infections acquired by patients while they are receiving health care for other conditions are a cause of illness and death around the globe. Such healthcare-associated infections (HAI) can occur in any healthcare facility, including hospitals, ambulatory surgical centres, end-stage renal disease facilities, and long-term care facilities. In this context, surface mediated spreading of pathogens is of ongoing concern. Decontamination of bacteria and viruses can be done by simple means using solutions of ethanol, hypochlorite, peroxide, or bleach; or even soap and household cleaning products. However, such methods are difficult to apply, time consuming, and most importantly short-lasting. Antipathogenic surfaces have one or more of the following features: They prevent microorganisms from attaching to the surface, inhibit biofilm formation, kill pathogens by release of antibacterial agents and can provide an alternative to disinfection.
The overall aim of the project is to combine the innovation of making transparent and dual functional photocatalytic TMOs and super-acid thin films, with the technical challenge of bringing the technology onto a flexible polymer web (PET film). The surface functionalized TMO/PET film will be iteratively tested for its anti-pathogenic properties at a university hospital both for virus and multi resistant bacteria activity with the ambition to establish coating process conditions compatible with clinical requirements, taking care of socio-technical and socio-environmental effects.
In this project, Fraunhofer ISI will assess the socio-technical effects in the development and usage of the innovation in healthcare settings:
