How UV-C Light Kills Bacteria and Viruses
UV-C light is a powerful tool for eliminating bacteria and viruses due to its germicidal properties. The science behind UV-C light’s effectiveness lies in its ability to damage the DNA or RNA of microorganisms, rendering them unable to replicate and causing their ultimate destruction.
The Science behind UV-C Light’s Germicidal Properties
UV-C light, specifically in the wavelength range of 200 to 280 nanometers, possesses the highest germicidal effectiveness. When microorganisms are exposed to this type of light, the photons penetrate their outer cell walls and disrupt the genetic material inside, leading to the inactivation of the bacteria or virus. This process is known as photodimerization or photolytic cleavage.
Common Bacteria and Viruses Eliminated by UV-C Light
UV-C light has been proven effective against a wide range of common bacteria and viruses. Some examples include Staphylococcus aureus, Escherichia coli, Salmonella, Influenza, and Norovirus. These microorganisms can cause various illnesses and infections, and UV-C light offers a non-chemical and environmentally friendly solution for their eradication.
UV-C Light and its Effectiveness against COVID-19
Recent studies have shown that UV-C light can also be highly effective in neutralizing the SARS-CoV-2 virus, responsible for the COVID-19 pandemic. Whilst UV-C light cannot be used directly on human skin or surfaces, it can be utilized in specialized devices to disinfect air, water, and objects in hospitals, laboratories, and other high-risk environments.
