METHODS OF MAINTAINING AND USING A HIGH CONCENTRATION OF DISSOLVED COPPER ON THE SURFACE OF A USEFUL ARTICLE

摘要

A method for maintaining and using a high concentration of dissolved copper on a surface of a useful article by providing a copper surface without coatings thereon, which increase the wetting angle and which isolate the copper surface and which has a surface roughness between 2 and 50 micro inches Ra, so as to kill microbes thereon.
