Ultraviolet or UV is a form of light, that is invisible to the human eye. The biggest natural source of the UV is the sun. UV comes in different wavelengths, the shorter the wavelength, the more harmful the UV radiation is. We are exposed to low levels of UV light from the sun’s rays every day, but much of the UV energy is absorbed by the ozone layer.
Ultraviolet is classified into three wavelength ranges, UV-A (315 nm to 400 nm), UV-B (280 nm to 315 nm), and UV-C (100nm to 280nm). Only UV-C is strong enough to incapacitate bacterias and virus.
The high energy from short wavelength UVC light is absorbed in the cellular RNA and DNA, damaging nucleic acids and preventing microorganisms from infecting and reproducing. This absorption of UVC energy forms new bonds between nucleotides, creating double bonds or “dimers”. Dimerization of molecules, particularly thymine, is the most common type of damage incurred by UVC light microorganisms. Formation of thymine dimers in the DNA of bacteria and viruses prevents replication and ability to infect.
According to Stuart Levy, a microbiologist from Tufts University School of Medicine, antibacterial products leave surface residues, creating conditions that may foster the development of resistant bacteria. For example, after wiping grocery items with antibacterial cleaner, active chemicals linger behind and continue to kill bacteria, but not necessarily all of them. The bacteria that survives will reproduce as their weaker relative perish. “What does not kill, makes you stronger”.
On the other hand, UVC is capable of inactivating microorganisms, such as bacteria, viruses and protozoa. It deactivates the DNA of bacteria, virus and other pathogens.It destroys their ability to multiply and cause disease. In fact, when the organism tries to replicate, it dies. It is a physics based approach in killing germs.
Ultraviolet C is the most powerful and highest energy type of ultraviolet light, and UVC, the only wavelength known to be germicidal. Unlike liquid solutions etc, UVC disinfection, is a chemical-free process and leaves behind no residue. With this method of disinfection, nothing is added which makes this process simple, inexpensive and requires very low maintenance.
