Arizona State University has designed a revolutionary laser technology that can kill HIV and bacteria without damaging human cells and help reduce the spread of methicillin-resistant Staphylococcus aureus infectionhospitalsThe study was published in the recently published Journal of PhysicsCurrent laser therapies, such as ULTRAviolet therapy, indiscriminately kill viruses with human cells, which can cause skin aging, damage DNA and, worst of all, skin cancer, and are not 100 percent effectiveThe researchers used a shock-excited Raman scattering process, in which the resulting fly-second laser pulse sepulted the microbial's protein shell to produce a deadly vibration, destroying the microbe, in a process similar to that of high-bass noise that shatters broken glassExperiments show that by carefully tuning the light wavelength and pulse width of infrared lasers, the coherent vibrations excited can cause no damage to human cellsThe main reason, the researchers speculate, may be that human cells are not made up in the same composition as protein shells of viruses and bacteriaThe femtosecond laser can be used to disinfect blood or biological materials or to treatof blood-bornediseases such as AIDS and hepatitis(Reporter Feng Weidong)
