Jakarta, CNN Indonesia –
Israeli Tel Aviv University researchers stated corona virus can be killed efficiently, quickly, and cheaply using a transmitter diode sinar ultraviolet (UV). Researchers believe UV-LED technology will soon be available for personal and commercial use.
The findings are the result of disinfection studies through UV-LED radiation with different wavelengths or frequencies in viruses from the coronavirus family. The study has been published in the Journal of Photochemistry and Photobiology B: Biology.
Launch EurekAlert, the researchers tested the optimal wavelength for killing the coronavirus. Researchers used the HCoV-OC43 corona virus as a substitute for SARS-CoV-2.
They found that 285 nanometer (nm) light waves were more effective at disinfecting viruses such as those at 265 nm waves.
The disinfection process takes less than half a minute to destroy more than 99.9 percent of the coronavirus. This result is claimed to be significant because 285 nm LED bulbs cost much less than 265 nm LED bulbs, and 285 nm LED bulbs are also more readily available.
Launch Science DailyResearch leader Hadas Mamane said the industry can make adjustments to the research findings. For example, he said the industry made UV = LED robots.
In fact, he said that the vacuum until the air conditioning system uses UV-LEDs to kill the corona virus. Mamane believes that the technology will also be available for use in the near future.
Researchers warn that it is very dangerous to try to use the iituni method to disinfect indoor surfaces. To be fully effective, the system must be specially designed so that a person is not directly exposed to light.
In the future, researchers will test a number of ways to kill bacteria and viruses on surfaces, air and water.
Researchers also say UV LED is an emerging technology and a source of UV for pathogen inactivation. UV irradiation is a common method for inactivation of pathogenic microorganisms, including viruses. Inactivation by UV can occur via several mechanisms.
The mechanism of UV inactivation depends on the UV wavelength used and for at least some pathogens, UV sources with multiple emission peaks, for example preassure lamps are being found to produce more effective inactivation.
