Abstract:
1. A process for producing a self-regulating sterilization system adapted for subsequent maintenance-free sterilization, said process comprising the steps of: (a) oxidizing a noble metal surface of a base material comprising noble metal in an acidic solution and then (b) treating the noble metal surface of step (a) with an aqueous salt solution, whereby slightly soluble noble metal salts or a mixture of noble metal salts of different solubility products are formed on the noble metal surface, which salts have grown directly on the base material; wherein noble metal ions are released from said noble metal surface and replenished from the noble metal surface of the base material during sterilization to produce a self-regulating and maintenance-free sterilization system.
