UV-A radiation commonly damages DNA in an oxygen-dependent manner that involves photosensitization. This leads to the production of a free radical that then interacts with and oxidizes DNA bases. These oxidized bases don’t pair correctly during replication, resulting in mutations (Figure 1). ...
but they are not resistant to Ultraviolet light (UV). Emitting both UV-C at 270 – 280nm and UV-A at 380 – 405nm, the Clearlight®UV Wand damages the DNA and RNA in bacteria and viruses rendering them harmless. Using high powered LED’s, the UV Wand allows you to disinfect up ...
Pulsed UV light is an emerging technology, which can be used for the inactivation of this pathogen in milk in a relatively short time. Pulsed UV light damages the DNA of the bacteria by forming thymine dimers that lead to bacterial death. The effect of sample distance from the quartz window...

There are two main ways that UV light accomplishes this. First, bacteria are living organisms, and UV light damages their DNA. When bacterial DNA is damaged, bacteria can’t complete two key reproductive processes known as transcription and replication that allows them to make more bacteria (3...
The mechanism on which UV light disinfection is based has to do with a phenomenon where (short-wavelength) ultraviolet light damages the DNA of exposed microorganisms. This damage disrupts their ability to perform vital cellular functions. And as a result, the organisms die. ...
Germicidal lights such as UV-C lights use the power of ultraviolet light to eliminate harmful pathogens, bacteria, viruses, and other microbes from the air as well as from the surfaces in a defined space. It damages the RNA and DNA of pathogens and disinfects the space quickly. It breaks ...

The threeLEDlamps have a bigger hump but it’s at about400 nm, so the peak is straddling UVA and visible light What doses? Now let’s look at the doses of these wavelengths. All of the studies foundminimal UVB, which is reassuring because UVB directly damages DNA, and is more strongl...
UV light rapidly inactivates microorganisms through a physical process. ExposingLegionellato certain wavelengths of UV light damages the DNA and renders them unable to reproduce. MostLegionellaspecies are sensitive to UV light, meaning the UV dose requirem...
