With schools taking precautions against COVID-19, an effective tool in their arsenal is a new type of “germicidal” LED fixture. This specialized, enclosed LED fixture draws in air and irradiates it ...

To disinfect a surface, you can illuminate it with a blast of ultraviolet (UV) light, which is bluer than the human eye can see. But to specifically inactivate SARS-CoV-2, the virus that causes ...

How ultraviolet light (UV) works as a disinfection technology depends upon the wavelength(s) being employed. The UVC band with a wavelength of 200-280nm has emerged as a viable solution for interior ...

This is the first study in the world conducted with LEDs of this wavelength, and the results confirm that the 226 nm UVC LEDs are able to quickly inactivate SARS-CoV-2 while having significantly less ...

When winter chill strikes, people stay indoors more often, giving airborne pathogens -- such as SARS-CoV-2 and influenza -- prime opportunities to spread. Germicidal ultraviolet (GUV) lamps can help ...

A bus being treated with ultraviolet light in Shanghai, China. Although types of UV light are already in use to decontaminate vehicles and indoor spaces, the wavelengths used are dangerous to people.

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which is the virus responsible for the coronavirus disease 2019 (COVID-19), has infected more than 186 million people worldwide and ...

The recognition that respiratory pathogens which cause COVID-19 were transmitted through airborne mechanisms was a critical insight into the nature of the disease and the need to decontaminate ...

In a fight to slow the global spread of Covid-19, which has already claimed more than one-million lives worldwide, researchers continue to look for ways to slow or kill the virus. Startup NS Nanotech ...
