A method that zaps airborne viruses with a narrow-wavelength band of UV light reveals a pledge for reducing the person-to-person spread of COVID-19 in indoor public locations.
The innovation uses lights that release continual, low dosages of a particular wavelength of UVGI system [ระบบ uvgi, which is the term in Thai], referred to as far-UVC, which can eliminate viruses as well as bacteria without hurting human skin, eyes, as well as various other cells, as is the issue with standard UV light.
Far-UVC light has the prospective to be a game-changer. It can be securely utilized in occupied public spaces, as well as it kills microorganisms airborne before we can breathe them in
A study group’s experiments have revealed far-UVC reliable in eradicating two kinds of airborne seasonal coronaviruses, the ones that create cold and coughing. The scientists are now examining the light against the SARS-CoV-2 virus.
The team formerly discovered the technique efficient in inactivating the airborne H1N1 flu virus, as well as drug-resistant bacteria. And also, several long-term types of research on pets as well as human beings have confirmed that exposure to far-UVC does not trigger damage to the skin or eyes.
If extensively used in busy public places, far-UVC technology can offer an effective threat for future epidemics and pandemics; also, when researchers create a vaccine against the infection that creates COVID, it will not shield versus the following novel virus.
Scientists have known for decades that germicidal UV light, wavelength around 254 nm, has the capability to eliminate infections, as well as germs. Health centers and laboratories usually utilize germicidal UV light to decontaminate empty rooms, along with other tools. Yet standard germicidal UV light cannot be used in the existence of people as it can reasons illness to the skin, as well as.
In contrast, far-UVC light, which has an extremely short wavelength, cannot reach or damage living human cells in the variety from 205-230 nm. However, these wavelengths can still penetrate, as well as eliminate very small infections and microorganisms drifting airborne or on surface areas.
