Abstract: The present disclosure relates to a fiber material having an antimicrobial effect, comprising fibers of regenerated cellulose and/or regenerated cellulose derivatives and at least one antimicrobial agent component. The present disclosure also includes a method of producing a fiber material having an antimicrobial effect, a fiber material produced by the method, and the use of the fiber material. The agent component of the fiber material comprises silver (Ag) and ruthenium (Ru), wherein silver and ruthenium are in electrical contact with one another and embedded in and/or at least partially surrounded by the cellulose and/or cellulose derivative fibers. The fiber material has not only antimicrobial properties, but also deodorising and/or odor-neutralising properties. In particular, the durability of the efficacy of the hygiene fibers is surprising.

Abstract: The invention relates to the production and use of novel bioactive devices and metallic coatings for example for sterilizing, disinfecting, and decontaminating water or aqueous solutions. The known oligodynamic effect of silver for reducing the amount of germs is thereby improved and increased by combining silver with ruthenium and a vitamin or derivative thereof. The novel properties of these bioactive metal surfaces lead to faster and more efficient killing of microorganisms. Simultaneously, these novel bioactive metal surfaces prevent infestation by microorganisms and attachment or permanent deposition of problematic biomolecules such as for example DNA, RNA, or proteins. A self-cleaning surface is thus obtained, which very quickly and efficiently and over extended periods of time sterilizes water and aqueous solutions when they come in contact with said surface.

Abstract: The invention relates to a device (1), in particular for protecting and for cleaning the bladder lumen, consisting of at least one functional body (2) which can be spatially expanded in a variable manner and can be modified at least partially from a small state into a larger state. Said device (1) protects the bladder lumen from bacterial invasion when the functional body (2) is inserted into the bladder and helps an infected bladder during mechanical cleaning and subsequent healing. The invention also relates to the use of the device (1) for medical, in particular prophylactic and therapeutic purposes.
