Physicists in Arizona State University have designed a laser technique Treatment 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. Current UV treatment can cause ageing of the skin, damage to the DNA or skin cancer and are not very effective. Femtosecond laser pulses, through a process called Impulsive Stimulated Raman Scattering (ISRS), produces lethal vibrations in the protein coat of microorganisms - destroying them. You can compare this effect to the high-pitched noise that shatters glass. The physicists in Arizona have undertaken experiments to show that the vibrations excited by infrared lasers with carefully selected wavelengths and pulse widths do no damage to human cells, most likely because of the different structural compositions in the protein coats of human cells vis a vis bacteria and viruses. So it looks like we will have a cure for AIDS and many other diseases and illnesses very soon. From Theengineer |
