Gold may be flashier, but now chemists are giving silver a chance to shine. They've figured out how to make silver nanoparticles that are even more stable than gold nanoparticles. Durable and easy to handle, gold nanoparticles are used for drug delivery, cell imaging and many other applications. Because silver is cheaper and more abundant than gold, it may seem like a more convenient nanomaterial. But unlike gold, silver degrades easily, which makes building stable silver nanoparticles extremely difficult.

Thousands of years before the discovery of microbes or the invention of antibiotics, silver was used to protect wounds from infection and to preserve food and water. The alluring metal - which was fashioned into a multitude of curative coins, sutures, foils, cups and solutions - all but vanished from medical use once physicians began using anti-bacterial drug agents to fight sickness in the 1940s. But now, as bacteria grow increasingly resistant to these medications and new pathogens invade hospitals, some doctors are turning once again to the lustrous element that Hippocrates prescribed for patients in ancient Greece.
