A team led by physicist Chris Barty of the University of California, Irvine is researching the use of diodes from Blu-ray digital videodisc devices as deep-ultraviolet laser photon sources to rapidly disinfect surfaces and indoor air.
Barty, UCI Distinguished Professor of Physics and Astronomy, said that such UV-light sterilizers would be cheap compared to current medical- and scientific-grade systems and that it would be possible to deploy them almost anywhere.
“If these sources are successful, I think you could build them into a mask and clean the air that’s coming in and out of you,” he said. “Or you could set these things up in the air circulation ducts of major buildings, and the airflow that goes…READ MORE
