| Résumé : |
In the projects described here, it was possible to successfully produce novel fibers containing photosensitizers, which could be detected in activity measurements. Air filters made from these fibers (AntiFil project) already showed first satisfactory results in the reduction of germs, whereas satisfactory results in liquid filtration (DynaFil project) could not yet be achieved. The next step will be to apply the additives to the fibers by other methods in order to reduce the path length to the germs to be killed and to increase the concentration of the freely available reactive species. |
