How would it be if the viruses causing HIV and hepatitis C could be zapped out from the blood stream of an infected patient? No, this is no another Hollywood creation of medical wizard, but efforts of a team of scientists, who knows no word synonym to ‘impossible.’
\n
\nA team of researchers have come up with a new challenge<\/a> with the use of lasers. Yes, they have meticulously used ‘laser’ to blast viruses out of blood!<\/p>\n

The new innovative technique uses a low-power laser beam with a pulse lasting just fractions of a second to rid isolated blood of dangerous pathogens<\/strong> – it eventually brings challenges in disinfecting blood for transfusions, and perhaps HIV and hepatitis C s well.<\/p>

\n<\/a>\n<\/div>\n\n

Blood transfusion<\/a> always leaves the one receiving it with the risk of developing the infection, as the prevailing techniques, which use UV irradiation and radioisotopes, can leave a trail of blood components mutated or damaged, or both.<\/p>\n

Johns Hopkins University student Shaw-Wei David Tsen says,<\/p>\n

Our laser repeatedly sends a rapid pulse of light and then relaxes, allowing the solution surrounding the virus to cool off. This significantly reduces heat damage to normal blood components.<\/p>\n

I had to repeat the experiment several times to convince myself that the laser worked this well.<\/p><\/blockquote>\n

So, once proved successful, the new laser technique can eventually replace the ultrasound techniques by penetrating energy-absorbing water surrounding the viruses, followed by vibrating the pathogen directly.<\/strong><\/p>\n
