Treatment of mucosal membranes
The invention relates to the use of one or more antimicrobial metals preferably selected from silver, gold, platinum, and palladium but most preferably silver, formed with atomic disorder, and preferably in a nanocrystalline form, for reducing inflammation or infection of the mucosal membrane. The antimicrobial metal may be formulated as, or used in the form of, a nanocrystalline coating of one or more antimicrobial or noble metals, a nanocrystalline powder of one or more antimicrobial or noble metals, or a liquid or solution containing dissolved species from a nanocrystalline powder or coating of one or more antimicrobial or noble metals.
