Extended data
Ultraviolet sterilization is the most effective method to destroy the molecular structure of DNA (deoxyribonucleic acid) or RNA (ribonucleic acid) in bacterial viruses, resulting in the death of growing cells and/or regenerative cells, thus achieving the effect of sterilization and disinfection. Especially when the wavelength is 253.7, ultraviolet rays have the strongest bactericidal effect.
