Like werewolves and vampires, bacteria have a weakness: silver. The precious metal has been used to fight infection for thousands of years — Hippocrates first described its antimicrobial properties in 400 bc — but how it works has been a mystery. Now, a team led by James Collins, a biomedical engineer at Boston University in Massachusetts, has described how silver can disrupt bacteria, and shown that the ancient treatment could help to deal with the thoroughly modern scourge of antibiotic resistance. The work is published today in Science Translational Medicine.
“Resistance is growing, while the number of new antibiotics in development is dropping,” says Collins. “We wanted to find a way to make what we have work better.”
Collins and his team found that silver — in the form of dissolved ions — attacks bacterial cells in two main ways: it makes the cell membrane more permeable, and it interferes with the cell’s metabolism, leading to the overproduction of reactive, and often toxic, oxygen compounds. Both mechanisms could potentially be harnessed to make today’s antibiotics more effective against resistant bacteria, Collins says.
Why does silver kill microbial cells?

Well now. Haven't people on ATS been extolling the virtues of colloidal silver for a while now?
And guess what folks. Now we have some Science to be back those claims up.
But I have a question. Anyone have their skin turn gray from taking too much silver?
I also seem to recall people screaming bloody murder over cloud seeding with silver iodide, again with the toxicity being a question when it gets into ground water.
In the 1990s, for example, a heart valve made by St. Jude Medical, based in St. Paul, Minnesota, included parts covered with a silver coating called Silzone to fight infection. “It did a fine job of preventing infection,” says Fowler. “The problem was that the silver was also toxic to heart tissue.” As a result the valves often leaked.
Before adding silver to antibiotics, “we’ll have to address the toxicity very carefully”, says Fowler. Ingesting too much silver can also cause argyria, a condition in which the skin turns a blue-grey color — and the effect is permanent.

NO! that silly man use'd salty water to make it work faster.
you must use the cleanest water you can get.
use a 1 micron filter. or use distilled water.
Not the De'ionized water.
All you need is two silver wire and a 9 volt battery.
best to use 3 * 9 volt battery and hot water.
and you Must swop the polaritys of the wires each time you use it.
as they slowly dissolve.
Silver is non toxic........
dont use Gold. it is toxic.

Silver Sulfadiazine (SSD) is an excellent dressing for burns. I have used it on other cutaneous wounds with marvelous results. Probably one of the best (efficacious) medicated ointments ever formulated, and one I consider a "must-have" for around the house. Just my opinion, YMMV.
