Seoul Viosys Announces Violeds Also Sterilizes Omicron Variant

ANSAN, South Korea–(BUSINESS WIRE)–Seoul Viosys (KOSDAQ: 092190), a company specializing in optical semiconductors, announced an experimental result confirming that its Violeds technology sterilizes 99.99% of the Omicron variant (SARS-CoV-2 Variant: B.1.1529) in one second , which is spreading all over the world .

Seoul Viosys conducted the Omicron sterilization test at Virology Research Institute of Korea University College of Medicine, and it was confirmed that the Omicron virus exposed to Violeds LED was 99.99% sterilized in a single second.

Seoul Viosys has been conducting various sterilization experiments using its Violeds technology since 2019. In July 2021, in a joint experiment with a research team from Korea University, Violeds was confirmed to sterilize (inactivate) the variant Delta (SARS-CoV-2: B.1.617.2) 99.3% in one second. Seoul Viosys bio research team released research data that the air purifying sterilizer with Violeds technology applied could reduce the risk of airborne infection by one-thirtieth. In November 2021, Seoul Viosys provided free air purifying sterilizers to 300 small shops that barely managed to make a living during the COVID-19 pandemic, and no confirmed cases were found in any of the shops where air purifying sterilizers are installed according to a survey of shop owners.

In addition, during CES in January 2022, portable air purifiers (model name: VAC) with applied Violeds technology were installed in conference rooms, restaurants and vehicles, and thanks to this, no case confirmed occurred among Seoul Viosys executives and employees.

Violeds is a clean technology that prevents the growth of viruses and bacteria thanks to ultraviolet (UV) LEDs, which have a sterilizing and deodorizing power. Not to mention air purifiers and air conditioners, this technology can also be applied to air conditioning systems in buildings and automobiles, reducing the possibility of infection caused by airborne droplets and keeping the indoor environment pleasant. by circulating the indoor air.

“Given the results of this Omicron test, we expect that continuously emerging variants of COVID-19, such as Deltacron, can be completely sterilized using Violeds products,” a Seoul official said. Viosys. “We will continue to apply Violeds technology to various products to create an environment where people can breathe clean and safe air at home as well as in restaurants, transport facilities and multi-purpose facilities.”

He also added, “Violeds is an innovative sterilization technology that we have developed and started mass-producing for the first time in the world, and no one can produce it without permission to use the patents of Seoul Viosys, its SETi subsidiary in the United States. , and NS (Nitride Semiconductor), a strategic partner in Japan.
