Columbia University's Dr. David Brenner Brings in a Team to Make Far-UVC Research a Reality and Kill COVID-19

Dr. David Brenner is a researcher at Columbia University who says he may have a "public health breakthrough" in the fight against the novel coronavirus.

He has discovered that a certain kind of light can kill airborne viruses, including some types of coronavirus. His research has since expanded specifically into its effectiveness against COVID-19.

As the director of the Center of Radiological Research at Columbia University, Dr. Brenner has been studying ultraviolet light, also known as UV light, as a potentially life-saving weapon against the spread of viruses.

UV light is known for its germicidal killing properties and is used to clean equipment and hospital areas. But it is also dangerous to humans because it can penetrate the skin and cause cancer, as well as cataracts.

However, that's not the case with a narrow band of UV light called far-UVC light.

"It can't get through any of the living cells of our skin," said Dr. Brenner. "That's why it's safe for human exposure."

Earlier this year Brenner was testing the ability of far-UVC light to kill airborne viruses in preparation for the upcoming flu season. When the coronavirus outbreak hit, Brenner ran additional tests to determine whether far-UVC light kills those viruses in the air as well.

"We saw we can kill 99% of the virus with a very low dose of far-UVC light," Brenner said.

Brenner's research team has already tested two seasonal coronaviruses, and is currently testing the current strain, SARS-CoV-2.

"There's no reason to believe it's going to be different from these results," he said.

Dr. Brenner envisions them being used in public places like airports and train stations, as well as in hospitals and schools. This is where Dr. Brenner's business team has entered the scene to work with Dr. Brenner to commercialize and scale his research.

"Right now there is no real approach to trying to reduce the amount of viruses in a room where people are and somebody sneezes and coughs," he said. "If you could actually decontaminate the air around you pretty quickly, that would be a real plus."
