The Science

UV LIGHT EXPLAINED

UV-A, UV-B, and UV-C are different regions of the ultraviolet (UV) spectrum, distinguished by their wavelengths and their effects on living organisms.
UV-A is associated with long-term skin damage
UV-B is primarily responsible for sunburns and skin cancer risk
UV-C is largely absorbed by the atmosphere and is used for germicidal applications.

 

HOW DOES NEUTRALIZE WORK?

UV-C light works to neutralize living microorganisms such as viruses, bacteria and pathogens, through a process called germicidal irradiation. 

When bacteria are exposed to UV-C light, the photons in the light interact with the DNA or RNA molecules within the bacterial cells. This interaction causes structural changes in the genetic material, specifically forming bonds between adjacent nucleotides. These bonds, known as thymine dimers, disrupt the normal functioning and replication of the genetic material.

As a result, the bacteria are unable to perform vital cellular functions or reproduce effectively. The DNA or RNA damage inflicted by the UV-C light is typically severe enough to lead to the bacteria's death or render them unable to cause infections or diseases.

UV-C light is particularly effective in neutralizing viruses, bacteria and pathogens because it can penetrate the outer protective layers of bacterial cells, reaching the genetic material within. This makes UV-C light a powerful disinfection tool in various applications, including water treatment, air purification, and surface disinfection.
