How does UV light sanitize surfaces?
In: Chemistry
UV light is a short enough wave length that it can penetrate into cells/viruses. When it does, it causes damage to the pathogen’s DNA. Essentially it gives pathogens supercharged cancer. It damages bacterial/viral DNA so badly that the cell can’t replicate and dies. Which is why most UV sterilization protocols are a minimum of 15 minutes, sometimes up to an hour, to make sure enough damage is done.
