We first heard about the disinfecting powers of UV-C light (ultraviolet light with a wavelength between 200 and 280 nanometers — and the same light that causes sunburn and skin-cell mutation in humans ...

Ultraviolet (UV) light is a type of radiation. It has more energy than radio waves or visible light but less energy than X-rays or gamma rays. You can be exposed to UV light via natural sunlight or ...

Ultraviolet light has a long history as a disinfectant, and the SARS-CoV-2 virus, which causes COVID-19, is readily rendered harmless by UV light. The question is how best to harness UV light to fight ...

As hospitals and health systems work to reduce healthcare-associated infections, a number of harmful pathogens, such as Clostridium difficile, may evade traditional disinfectants and manual cleaning ...

A long-neglected technology offers new hope to Canadians that viruses can be eradicated. The solution is ultraviolet light, invisible to the human eyes, but deadly to pathogens. And its proper ...

We’re living in strange times, and the few things we know we can do to protect ourselves involve washing our hands and sterilizing surfaces and objects regularly. But who wants to waste all that paper ...

A novel technology that utilizes light of different wavelengths to control cellular functions by inducing reversible assembly and disassembly of molecules has been developed. This breakthrough could ...

Doctors use UV light therapy to treat various common skin conditions, such as psoriasis and eczema. They consider it effective and safe, although it may cause short- and long-term side effects, ...
