Experts at the Graz University of Technology and the Research Center Pharmaceutical Engineering (RCPE) have developed a solution which has already led to several patents and awards.
"Photodynamic Disinfection certified Technology" (PDcT) makes use of the photodynamic effect which enables a dye to react to special wavelengths of light. In the reaction, highly reactive oxygen is formed which prevents the growth of undesirable germs.
The process is used in dental medicine as the so-called antibacterial photodynamic therapy. This method of disinfection has now been expanded to include specially dyed clothing.
The Austrian company Ortner Reinraumtechnik applied for a patent for this process, and was recently given the special ECONOVIUS prize within the context of the State Prize for Innovation 2016 as well as the Carinthian Innovation Award.
