The hygiene requirements in healthcare increase due to the high number of nosocomial infections and the growing spread of antibiotic resistant microorganisms in healthcare. A proper surface cleaning and disinfection provides a contribution to the reduction of nosocomial infections.

Here also floor cleaning or disinfection has to be taken into account, because floors make up the largest proportion of all surfaces and in addition their germ contamination can be higher than the contamination of other areas.

As the floors are quickly recontaminated with microorganisms after cleaning and disinfection due to permanent use, it must be assumed that the hygiene status can be improved by renewable systems which work sustainably disinfecting between two cleaning or disinfection measures. Therefore, a completely new approach to the development of such systems was examined.

The approach is based on renewable antimicrobial peptide primer systems for ensuring a sustainable hygiene of elastic floorings in the health care sector. These systems consist of antimicrobial peptides as germ-inactivating substances and a primer system with pH-dependent cationic charge.
