AfricaPress-Kenya:<\/strong> With coronavirus cases around the world now at over 6.2 million, scientists have been working around the clock to find a way to halt the pandemic.<\/p>\n

Now, scientists at Penn University, the University of Minnesota and two Japanese universities claim that coronavirus could be killed by a handheld UV light device.\u00a0Ultraviolet radiation in the 200 to 300 nanometre range is known to destroy the virus.<\/p>\n

And while devices with these doses do currently exist, they require high power, have a relatively short lifetime, and are bulky.Instead, the researchers say that a handheld device with the same UV levels could be the perfect solution for keeping the public protected while on the go.Dr Roman Engel-Herbert, one of the authors of the study, said: \u201cYou have to ensure a sufficient UV light dose to kill all the viruses.<\/p>\n

This means you need a high-performance UV LED emitting a high intensity of UV light, which is currently limited by the transparent electrode material being used.\u201dUnfortunately, developing such a device is easier said than done.<\/p>\n

Joseph Roth, who also worked on the study, added: \u201cThere is currently no good solution for a UV-transparent electrode. Right now, the current material solution commonly employed for visible light application is used despite it being too absorbing in the UV range.<\/p>\n

\u201cThere is simply no good material choice for a UV-transparent conductor material that has been identified.\u201dThe team is currently in the process of developing a handheld UV device, although it remains unclear when it will be ready.<\/p>\n

Mr Roth added: \u201cWhile our first motivation in developing UV transparent conductors was to build an economic solution for water disinfection, we now realize that this breakthrough discovery potentially offers a solution to deactivate COVID-19 in aerosols that might be distributed in HVAC systems of buildings.<\/p>\n

\u201cOther areas of application for virus disinfection are densely and frequently populated areas, such as theaters, sports arenas and public transportation vehicles such as buses, subways and airplanes.\u201d<\/p>\n","protected":false},"excerpt":{"rendered":"
