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). ...

Research in the late 1800s and early 1900s proved that exposure to specific wavelengths of ultraviolet (UV) light damages DNA, so with adequate exposure and intensity, cells of microorganisms lose the ability to function, and the microbes die. The confirmation of the science opened the door to...
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 ...
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...

UV light is germicidal because it inactivates microorganisms by destroying nucleic acids and disrupting their DNA with its short wavelength. In addition, oxygen can also absorbed energy from UV light to form ozone for disinfection. (Image: Pixabay) ...
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...
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. ...
