low-power laser vs virus infection

The researchers applied pulses of purple-coloured light lasting just 100 femtoseconds (10-15 seconds) to viruses called M13 bacteriophages. It takes just a single pulse to destroy the viruses completely, say the researchers.

"In addition, we believe that the method may be especially important in designing novel treatments for blood-borne viral diseases," he said. "For example blood dialysis allows us to irradiate a patient's blood outside the body and potentially cleanse it of infectious virus particles before reintroducing it into the patient. In this way, we could reduce mortality associated with diseases like hepatitis C and AIDS."

The team now plans to test the efficacy of its technique in killing a wide range of deadly viruses, including HIV and hepatitis C. "We also plan to conduct further tests on the effects of the low-power visible laser on mammalian cells to determine any potential side effects and confirm that it selectively kills viruses," said Tsen.

I believe truth and principle do matter. If you have to sacrifice them to get the results you want, then the results aren't worth it.
