Physicists in Arizona State University have designed a revolutionary laser technique which can destroy viruses and bacteria such as AIDS without damaging human cells and may also help reduce the spread of hospital infections such as MRSA.
The research, published on Thursday November 1 in the Institute of Physics' Journal of Physics: Condensed Matter, discusses how pulses from an infrared laser can be fine-tuned to discriminate between problem microorganisms and human cells.
Current laser treatments such as UV are indiscriminate and can cause ageing of the skin, damage to the DNA or, at worst, skin cancer, and are far from 100 per cent effective.
Femtosecond laser pulses, through a process called Impulsive Stimulated Raman Scattering (ISRS), produces lethal vibrations in the protein coat of microorganisms, thereby destroying them. The effect of the vibrations

Yeah, they’ll sell ‘em at Home Depot.
i want to pre-order mine from Ron Popeil.

There are an awful lot of medical possibilities happening right now. One that got my attention recently was a purely mechanical, not really medical idea on how to radically strip plaque from capillaries without harm.
That is, other than restricting blood vessels, chunks of plaque can break off and give heart attacks and strokes. But what if you could use the equivalent of Drano to strip it all out, but without the risk?
Since we do have chemicals that could do that, act like Drano to plaque deposits, in the blood, what was needed was a way to get them safely out of the body.
The possible answer is artificial blood. It is a substance that carries far more oxygen than real blood, but could harm the internal organs, which is why it is not widely used.
What if it didn’t flow *through* any organs? Say if a leg had phlebitis or severe plaque deposits, you could bypass its blood flow, then run artificial blood in a closed loop through the leg and back to a machine. The tissues would be heavily oxygenated, so would be a little risk of damage. Then you could inject the plaque or blood clot clearing agent into the artificial blood, completely removing them from the leg and filtering them out.
Only when the leg was “cleaned” of its problem, would you switch back to the patients regular blood system, flushing out any remaining artificial blood in the process.
The use of artificial blood in bypass surgeries like this could really advance things like microsurgery in a crushed hand, by preventing oxygen deprivation from damaging the tissues, but without passing it through the internal organs.
I'll wait for this guy, because you can probably get a second for free (only add S & H)
Y’all pull out your checkbooks and send those checks to this cat. Early investors welcome. We’re all gonna cash in!
I don’t know what the difference is between Femtosecond lasers and cold lasers is but the same sort of claim is made for cold lasers. Google it and you will find lots of sites selling them for both home and clinical use. Apparently lots of health care practitioners are using them. I have no idea if they work.
—Don’t Lase me bro’!
Where do they stick the laser?
thanks, bfl
