Sanitizing with UV Light
LED lighting is all the rage these days. Add some Ultraviolet (UV) to make UV-LED and voila – an antimicrobial disinfectant perfect for the pandemic. With germs a serious global concern, UV-LED is an easy option for sanitizing.
When LEDs are tuned to wavelengths between 405 to 425 nanometers (nm), bacteria, mold, mildew, and fungi are deactivated and inhibited. The antimicrobial space is full of manufacturers offering UV-LED as a disinfectant for viruses and bacteria.
Jennifer Brons, research program coordinator for Mount Sinai Health System’s Light and Health Research Center in New York, said, “COVID-19 has raised our consciousness regarding germ spread. Disinfection light is getting a renewed look and a renewed R&D.”
The Mount Sinai Health System’s Light and Health Research Center was launched in February and is part of the Icahn School of Medicine at Mount Sinai. Their mission is to research the influence of light on mental and physical health. UV disinfection technology is an aspect of study within the center.
Brons and her colleagues selected the least expensive and most widely available UV disinfectant products for their research. The UV-C wavelength was found in tests to be the most effective at bacterial and viral disinfection (roughly 1,000 times more.) Therefore, UV-A is a safer approach as UV-C can be damaging at high levels of exposure.
UV-LED is a newer technology; therefore, other UV-C lighting is being tested by the National Emerging Infectious Diseases Laboratories at Boston University for its ability to immobilize SARS-CoV-2, the virus that causes COVID-19. On contaminated surfaces, the manufacturer’s lab testing has shown a destroying rate of 99% against Sars-CoV-2.
UV-LED for water treatment is in high demand. UV-C is used to kill viruses, bacteria, and other pathogens in water within seconds. Oliver Lawal, president and CEO of AquiSense Technologies, said, “We offered a UV-LED water disinfection product five years before anyone else.” The company is also developing applications for air and surface decontamination.
Using light as a disinfectant is helpful to decontaminate germs and viruses within our environment. With more research, light sanitation is positioned for exponential growth.
