Nanosilver: Naughty or nice? | Science News for Students
Historians suspect that argyria could have been the origin of the term “blue blood” is used to describe people of noble birth. In earlier times, it was common for European nobillity to have skin that appeared to have a blue or greenish cast especially made obvious by their pale skin that were "untouched by the sun" - - another mark of status among the wealthy who didn't have to do labor outdoors.
Aristocrats were originally the only ones who could afford medicine, often in the form of colloidal silver (the liquid into which silver particles are suspended and was thought of as a cure-all for many different illnesses); could have a considerable number of silver coins and could have worn silver jewelry; and could have eaten off silver plates and used real silver cups and tableware which were later found to shed nano silver particles under a microscope. Hence, argyria was common only to those who were born with a silver spoon in their mouths.
Silver is as useful as it is beautiful. A natural antibiotic, it kills bacteria, mold, fungi, viruses, algae and other microorganisms.
People have recognized this benefit since ancient times. Ancient Phoenicians used silver vessels to keep water pure. In the absence of modern refrigeration, sailors then, threw silver coins into their milk to keep it from spoiling on long journeys and wealthy Romans ate with silver plates, knives, forks and spoons to keep spoiled food from making them sick. In fact, historians think that is how eating utensils came to be called “silverware.”
To this day,silver continues to play a role in medicine. Silver-coated bandages kill germs that might infect burns and other wounds.Breathing tubes are sometimes coated with silver to reduce the risk of patients on ventilators developing pneumonia from exposure to germs. Around 2005,companies started adding a new form of silver fashioned into minute particles, to everyday items like socks, toothbrushes, washing machines, vacuum cleaners and so on, as a "defense against bacteria that might make people sick" or cause stinky feet or bad breath. This form of silver came to be known as NANOSILVER.
