RayVio deep UV LEDs show strong disinfection performance in tests

* Surface-Air-Disinfection.jpgRayVio Corp., an advanced health and hygiene company, has today announced study results from efficacy testing of its deep ultraviolet (UV) LED solution for disinfection.

The study shows that RayVio's deep UV LEDs can eliminate bacteria found in hospitals and other buildings more quickly and to a higher degree than many of today's most common disinfection products, aiding in the fight against hospital acquired infections (HAI).

A single RayVio UV LED killed 99.9999% of the bacteria samples of Methicillin-resistant Staphylococcus aureus (MRSA), listeria and salmonella within 60 seconds. Even faster results or larger scale applications are achieved by using multiple LEDs.

Researchers irradiated samples of bacteria with RayVio's deep UV LED emission wavelength of 285 nanometers at a 10 millimeter distance. They measured the change in bacteria population after time intervals between five and 80 seconds. 99.99% bacteria were killed in five seconds and 99.9999% killed within 60 seconds.

The study was conducted at AEMTEK, a third party laboratory accredited by the American Association for Laboratory Accreditation (A2LA), which is recognised by the Food & Drug Administration (FDA).

"Recent outbreaks in hospital infections, including the rise of superbugs, underscore the critical need for improved disinfection solutions," said Dr. Yitao Liao, rayvio's chief innovation officer. "The study proves that RayVio's technology disinfects thoroughly and at record speed, which highlights the important role it can play in preventing illness around the world."

The results demonstrate that exposure to ultraviolet LED radiation effectively deactivates bacteria significantly faster and more completely than today's disinfection solutions. Hospitals often use chemical disinfectants that require several minutes to safely kill bacteria such as MRSA and salmonella. Common alcohol hand sanitizers take a minute or more for full effect and still only achieve 99.99% disinfection. Long exposure times increase risk of human error and incomplete disinfection.

Although conventional UV light sources such as mercury lamps can disinfect, they are bulky, fragile and contain mercury, a restricted hazardous material. RayVio's technology - with the most power per square millimeter of any deep UV LED - is portable and compact and can be integrated into a range of applications to disinfect catheters, physicians' mobile devices, door handles and much more.

RayVio, along with its partners, is developing UV LED disinfection solutions that are mobile, compact, mercury-free, instantaneous, and capable of disinfection in virtually any environment.

"Imagine being able to disinfect any surface, anywhere, any time, with an app on your mobile phone, that provides real-time feedback showing guaranteed surface coverage and disinfection efficacy, all with the same simplicity of using the flash on your mobile phone," challenges the company.

"We are making mobile disinfection possible, which will enable everyone to protect themselves, everywhere they go.

"With LED lighting becoming ubiquitous, UV LED disinfection options for virtually any LED lighting system become a reality... systems that are capable of disinfecting surfaces ranging from counter-tops, to lavatories on airplanes, to entire classrooms and hospital rooms.
