Nano silver solution (nAgs) has been investigated and used intensively in different fields due to its antimicrobial effect. There are various methods to prepare nAgs: mechanical, chemical, or physical. However, nAgs obtained from the above methods usually leave undesired chemicals in solution, limiting its antimicrobial activity. Meanwhile, the electrochemical method, utilizing anodic dissolution of metallic silver under high DC voltage to generate nAgs in double distilled water, giving highly pure product, is a new and promising technology. The method, using fundamentally different principles, results in nAgs with substantially different properties, is being able to prepare nAgs of equal concentration to that produced via chemical methods.
