Description ...

Silver often plays second fiddle to another precious metal, gold, but this element has special properties that deserve a good look. For example, of all the metals, pure silver is the best conductor of heat and electricity, according to the Jefferson National Linear Accelerator Laboratory. It's also the best reflector of visible light, which is why it is commonly used to make mirrors — though silver does tarnish and turn dark grey when exposed to air, requiring periodic polishing. Pure silver is too soft for products like jewelry and tableware, so the family's finest forks and knives are most likely sterling silver, an alloy of 92.5 percent silver and 7.5 percent copper (though sometimes other metals are used). Silver is also used in some electronics and batteries. Because the metal has antimicrobial properties, nanoparticles of silver can be woven into clothing to prevent bacteria from building up on deposits of sweat and oils, according to the Royal Society of Chemistry (RSC) . Silver's antimicrobial properties have put this element in the doctor's bag of tricks; according to Wounds International, silver has been used to prevent the infection of injuries for hundreds of years. Silver doesn't kill microbes in its metallic form, in which it is unreactive. The metal works against bacteria only in ion form — it must lose an electron to become positively charged. The positively charged silver ion interferes with bacterial cell walls and disrupts other microbial processes. Burn patients may use silver-antibiotic creams on their injuries, and some hospitals use silver-infused dressings for skin ulcers and other wound care. There are debates within the field, however, about the efficacy of these dressings, particularly after a 2010 review published in the Cochrane Database of Systemic Reviews found that they don't speed wound healing. A Wounds International working group of medical professionals, however, argued in 2012 that the dressings can be useful for localized infections. Some manufacturers have taken silver's antimicrobial magic as a marketing opportunity, creating silver-infused textiles that purport to stop smelly bacteria from setting up shop in the fabric.
