Far-UVC ultraviolet light, at wavelengths from 200-to-230 nanometers, deactivates viruses in the air and on surfaces but doesn't penetrate the skin far enough to reach live cells.

A walk in the desert and a curious discovery could have revealed that the secrets of alien life grow in the harshest conditions on Earth in the form of lichen.

How Far-UVC light could be key in curbing the next airborne pandemic 03:31. Five years ago, the COVID-19 pandemic first swept across the U.S., infecting millions and claiming hundreds of thousands ...

Ultraviolet light is well-known for its ability to kill germs, including ones that cause food to spoil. And while there doesn't tend to be any food-preserving UV light in our refrigerators, a new ...

NS Nanotech's ShortWaveLight™ 215 Emitter, the world’s highest-energy semiconductor ultraviolet light source, enables human-safe air and surface disinfection in occupied spaces with far-UVC light.

In contrast, dual-comb spectroscopy exposes the sample to broadband light from a frequency comb itself. As the input is broadband, the output is also broadband. However, the light passing through the ...

Ultraviolet (UV) sanitizers use UV rays to sterilize surfaces. UV sanitizers have been shown to work, with some devices eliminating nearly 99.99% of bacteria, fungi, and viruses that cause disease.

An ultraviolet photon-counting dual-comb spectrometer. Two ultraviolet frequency combs of slightly different pulse repetition frequencies are generated at very low light levels by nonlinear ...

Ultraviolet light is invisible to the eye, ... and with small sample sizes. We will need trials with rigorous ethical approvals to investigate the full far UVC impact on humans.

Conventional UVC light is currently used to sanitize surfaces in places like hospitals, but it's not shined directly at people, because it can harm the eyes and skin.
