Scientists have known for some time that silver ions (Ag+) are very good sanitizers:
Silver ions are used to sterilize recycled water in the space lab.
Silver ion-generating surgical dressings disinfect, promote healing and reduce pain.
Silver ion-generating fabric is employed in US military uniforms, sports wear and socks.
Silver ion-generating technology is used in new refrigerators, washers, wash-cloths, sponges and food containers.
Incorporated in high-end, designer products and marketed in the dollar economy, silver ion generators are very expensive. Yet, silver is not inherently expensive.
Why Silver? Or, more specifically, why have inexpensive, long-lived silver ion generators been developed by and offered within pro bono science?
Because silver’s many beneficial uses plead for its antimicrobial technology to be brought to the individual. Because people everywhere will benefit from being able to generate silver ions on site while learning how to use them responsibly.
