We all know that the violet light emitted by UVC LED chips can inactivate harmful microorganisms, but do you know exactly which pathogens it can target? Let’s take a closer look.
UVC ultraviolet light, especially in the wavelength range of 200 to 280 nanometers (commonly with a peak at 260 nm), is highly effective in killing a wide variety of microorganisms, including bacteria, viruses, fungi, and protozoa. Below are some common pathogens that UVC LEDs can effectively inactivate:
1. Bacteria
Escherichia coli (E. coli): Found in contaminated water and food.
Staphylococcus aureus, including methicillin-resistant Staphylococcus aureus (MRSA): A common antibiotic-resistant bacterium in hospitals.
Salmonella: One of the main bacterial causes of food poisoning.
Helicobacter pylori: Associated with stomach ulcers and gastric cancer.
2. Viruses
SARS-CoV-2 (COVID-19 virus): Studies have shown that UVC light can effectively inactivate this virus.
Influenza virus: Seasonal flu viruses can have their spread reduced through UVC exposure.
Hepatitis B virus (HBV): Inactivated by damaging the virus’s DNA.
Human Immunodeficiency Virus (HIV): Can be destroyed during the disinfection of medical instruments and blood products.
3. Fungi and Molds
Aspergillus niger: A common mold found in the air.
Saccharomyces cerevisiae: Controlled to prevent unwanted spread in food processing.
4. Protozoa
Giardia lamblia: Causes intestinal infections.
Cryptosporidium parvum: A common waterborne pathogen.
Note: While UVC radiation has proven to be highly effective against the above microorganisms, actual disinfection requires an adequate dose—meaning the right UV intensity and exposure time. Furthermore, proper safety measures must be taken when using UVC devices to prevent harm to human skin and eyes.
