How exactly does UV-C light kill germs and bacteria?
At Zygienic, our UV phone santiser uses Ultraviolet Germicidal Irradiation (UVGI) to disinfect your mobile devices. But what exactly is UVGI?
What is UVGI?
UVGI uses UV light of wavelengths 200 – 280 (UV-C) to disrupt the DNA of microorganisms. This destroys their nucleic acid so they aren't able to perform vital cellular functions. There are many areas where UVGI is being utilised ranging from disinfection in hospitals to air and water disinfection.
Ultraviolet is present in sunlight, making our sun a natural disinfectant to some extend. However, due to Earth's protective ozone layer, the presence of UV-C light at the surface level is weak. And this allows bacteria and microorganisms to grow.
We created a product that creates a contained environment where UVC light is focused, making it eliminate microorganisms such as bacteria, viruses, moulds and other pathogens.
UV-C application around the world
Dring the COVID period in 2020, Singapore has announced plans to deploy over 200 UV Disinfecting Robots that utilizes UVC to fight the virus.
