New uses for silver have been stemming from the health, energy, and electronic industries. Silver contains anti-bacterial properties and researchers have found that silver can be used as a biocide. Burn units in hospitals use bandages that release silver ions that help with healing and reduce the need for frequent dressing changes. Research on silver use in fuel cells and catalysts is well underway by the auto industry. Silver has a significant cost advantage when compared to platinum. The electronic industry is continuing to reduce the amount of gold used in bonding wires and plating. The industry is replacing it with silver, a cheaper and equally durable substitute. Silver coins that are investment grade 99.9% pure are permitted to be included in Individual Retirement Accounts.
