Ultraviolet (UV) light is a component of the electromagnetic spectrum that falls in the region between visible light and X-Rays.

This invisible radiation includes the wavelength range of 100 nm to 400 nm. UV light can be further subdivided and categorized into four separate regions:

• Far UV– 100 nm to 200 nm: These wavelengths only propagate in a vacuum
• UVC – 200 nm to 280 nm: Useful for disinfection and sensing
• UVB – 280 nm to 315 nm: Useful for disinfection, curing, tanning, and medical applications
• UVA (or “near UV”) – 315 nm to 400 nm: Useful for disinfection, medical applications, printing, curing, lithography, and sensing

As evident by multiple research studies and reports, when biological organisms are exposed to deep UV light in the range of 200 nm to 300 nm, the UV is absorbed by the DNA, RNA, and proteins.

Absorption by proteins can lead to rupture of cell walls and the death of the organism. Absorption by DNA or RNA (specifically by thymine bases) is known to cause inactivation of the DNA or RNA double helix strands through the formation of thymine dimers. If enough of these dimers are created in DNA, the DNA replication process is disrupted, and the cell cannot replicate.

It is widely accepted that it is not necessary to kill pathogens with UV light, but rather apply enough UV light to prevent the organism from replicating. 

UV-C has been proven to kill several strands of viruses (below are research studies demonstrating the effectiveness of UV-C light on SARS and MERS).

• Evaluation Of Inactivation Methods For SARS
• Stability Of SARS Coronavirus And Its Sensitivity To Heating And UV Irradiation
• Inactivation Of MERS-COV Using A Riboflavin-based And Ultraviolet Light-based Photochemical Treatment
