This pathogen Fighter eliminates germs fast. You need not use any dangerous chemicals, wipes, or harsh detergents. Simply “swipe away pathogens with light” and sanitize all your precious devices! UV-C light is germicidal – i.e., it deactivates the DNA of germs and thus destroys their ability to multiply. Specifically, UV-C light causes damage to the nucleic acid of microorganisms by forming covalent bonds between certain adjacent bases in the DNA. The formation of such bonds prevents the DNA from being unzipped for replication, and the organism is unable to reproduce. In fact, when the organism tries to replicate, it dies.
