How It Works

When exposing microorganisms to UV-C light, the light penetrates through their cell wall and disrupts the structure of their DNA molecules – prohibiting reproduction.

By deactivating the DNA of bacteria, viruses, and other pathogens, it destroys their ability to multiply and cause disease. 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.

Benefits

Ultraviolet (UV) light is produced by the sun and by special lamps. There are three types of UV light—UVA, UVB, and UVC. UVC light has the most energy of the three types. This energy destroys the genetic material inside viruses and other microbes. Therefore, UVC light is used for disinfection. UVC lamps and robots are commonly used to sanitize water, objects such as laboratory equipment, and spaces such as buses and airplanes. (Source: National Academy of Sciences)
