The invention relates to the production and use of novel bioactive devices and metallic coatings, e.g. for sterilizing, disinfecting, and decontaminating water or aqueous solutions. According to the invention, the known oligodynamic effect of silver to reduce the amount of germs is improved and increased by combining silver with ruthenium and a vitamin or the derivative thereof. The novel properties of said bioactive metal surfaces allow microorganisms to be destroyed faster and more efficiently while preventing microorganisms from infesting said novel bioactive metal surfaces and problematic biomolecules such as DNA, RNA, or proteins from attaching thereto or being permanently deposited thereon. A self-cleaning surface is obtained that very quickly and efficiently kills germs in water or aqueous solutions with which said surface enters in contact and keeps the water or aqueous solutions free from germs for extended periods of time.

L'invention concerne la production et l'utilisation de nouveaux dispositifs bioactifs et de revêtements métalliques, par exemple pour la stérilisation, la désinfection et la décontamination de l'eau ou des solutions aqueuses. Selon l'invention, l'effet oligodynamique connu de l'argent pour la stérilisation est amélioré et renforcé par la combinaison de l'argent avec du ruthénium et une vitamine ou leurs dérivés. Les nouvelles propriétés de ces surfaces métalliques bioactives permettent de détruire plus rapidement et plus efficacement les micro-organismes. En même temps, ces nouvelles surfaces métalliques bioactives empêchent la colonisation par des micro-organismes et la fixation ou le dépôt stable de biomolécules problématiques telles que, par exemple, l'ADN, l'ARN ou des protéines. On obtient ainsi une surface autonettoyante qui, lors du contact avec l'eau ou avec des solutions aqueuses, devient rapidement et efficacement stérile, et le demeure sur de longues périodes de temps.
