Getting your Trinity Audio player ready... Scientists have long known that ultraviolet light can kill pathogens on surfaces and in air and water. UV robots are used to disinfect empty hospital rooms, ...
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.
US labs NIST and DHS conduct thorough tests to show how different wavelengths interact with virus. To disinfect a surface, you can illuminate it with a blast of ultraviolet light. But to specifically ...

IEEE study improves design of avalanche photodiodes for photodetection in the ultraviolet wavelength
Geiger-mode avalanche photodiodes (GM-APDs) are highly sensitive light detectors, capable of detecting single photons. Photons of certain wavelengths, when absorbed by photodiodes, generate ...
A specific wavelength of ultraviolet (UV) light is not only extremely effective at killing the virus which causes COVID-19, but is also safer for use in public spaces, finds new research. A specific ...
