Ultraviolet (UV) lightemitting diodes (UVLEDs) can kill the novel coronavirus efficiently, quickly, and cheaply, according to a study which says the new innovation could be installed in air conditioning and water systems. The research, published in the Journal of Photochemistry and Photobiology B: Biology, assessed the disinfection efficiency of UVLED irradiation at different wavelengths on a virus from the family of coronaviruses, which includes the COVID19causing SARSCoV2. "The entire world is currently looking for effective solutions to disinfect the coronavirus," said Hadas Mamane, coauthor of the study from the American Friends of Tel Aviv University in the US. In order to disinfect a bus, train, sports hall, or plane by chemical spraying, the scientists said physical manpower is needed along with time for the chemicals to act on the surface. "Disinfection systems based on LED bulbs, however, can be installed in the ventilation system and air conditioner, for example, and sterilise the air sucked in and then emitted into the room," Mamane said.
