How does UV light sanitize surfaces?
In: Chemistry
UV light has a lot of energy per photon. Enough energy to knock electrons off many common chemicals that make up living things bodies. Once that happens you have what’s called a free radical, they like to react with anything they are near. It can also break bonds in chemicals necessary for life. So UV creates free radicals that go around and wreck the complex web of chemical reactions we call life. They are capable of screwing up most pathogens so badly that they just die. Every living thing can take a certain amount of UV but eventually it’s just too much for their system.
