BIOACTIVE, RUTHENIUM-CONTAINING COATING AND DEVICE

摘要

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.
