KILLER MRSA could be shot down by tiny 'silver bullets’, scientists claim.
The spray metal treatment could revolutionise the fight against the deadly superbug.
It involves showering wounds and hospital wards with microscopic particles of the metal.
Experts have long known silver is resistant to the superbug and is highly toxic to some other bacteria. It is already used in....
Particles of silver could be used against MRSA

Scientists have known for years that silver kills germs but it is most effective in the form of nanoparticles - tiny flecks
of metal containing just a few hundred atoms. But the problem is that nanoparticles are hard to make in a useful form. Now a team
of physicists at Leicester University have built a machine that can produce them by the bottle, which could potenially save
thousands of lives a year. Chris Binns, professor of nanoscience at Leicester, said the microscopic silver particles are small
enough to pass inside the germs and disrupt their inner workings - but they do not kill human cells. Just two or three
nanoparticles are enough to kill one germ cell. This means the nanoparticles could be a vital weapon in fighting the deadly
diseases caused by bacteria. The bacteria in the lungs of cystic fibrosis sufferers are especially hard to kill because a thick
coating of mucus protects them from drugs, but nanoparticles can pass through, said professor Binns. With the prototype £250,000
machine - about the size of a motorbike - the researchers have found a way to produce particles all the same size suspended in a
liquid, which means it can be put in an aerosol and breathed in. It could also be injected.
