UVC-based disinfection, often called, Ultraviolet germicidal irradiation (UVGI), is the use of ultraviolet (UV) light to kill or inactivate viral, bacterial, and fungal species. When UV-C light is incident upon the target, the incident photons are absorbed by DNA or RNA, causing inactivation of the DNA or RNA double helix strands through the formation of molecular lesions. When enough of these lesions are created, the replication process is disrupted, and the cell cannot replicate. Absorption by proteins can lead to the breakdown of the organism’s cell walls causing the cell to die. For most commercial applications, replication prevention is sufficient.
