Tel Aviv research: 99.9% of COVID-19 virus dead in 30 seconds with UV LEDs
The study is the first of its kind in the world.
DECEMBER 26, 2020
Ultraviolet radiation is a common method of killing bacteria and viruses.
Tel Aviv University proves coronavirus killed efficiently, quickly, cheaply
using ultraviolet (UV) light-emitting diodes (UV-LEDs) at specific frequencies
Prof. Hadas Mamane, head Environmental Engineering, Tel Aviv University's School of Mechanical Engineering, led study with Prof. Yoram Gerchman and Dr. Michal Mandelboim.
UV-LED bulbs require less than half a minute to destroy 99.9% of coronaviruses
The study is the first of its kind in the world
her team developed low-cost, decentralized, nonpolluting means to produce ethanol
and thereby an alcohol-based hand sanitizer – from municipal and agricultural waste
LEDs have wide range of wavelengths, known as A, B and C
UV-A emitted by sun, some human benefits, also causes sunburns, skin cancer
UV-B and C never reach humans because absorbed by earth’s ozone layer
UV-B and C effective in disinfection using UV-LED bulbs
UV LED bulbs can be installed in ventilation system and sterilize air circulation
also developing transparent coating sprayed on surfaces
can kill viruses using visible light LEDs
as it develops LED bulbs able to efficiently disinfect large surfaces and spaces
“Our research has commercial and societal implications,” Mamane said.
this technology is the future, by 2025 to become mainstream
