Dr Stella Sung Ph.D. published findings on the application of ultraviolet (UVC) light in germicidal wavelengths for disinfection of contaminated air and surfaces. In this analysis, the Sterile-Bright™ product line emerged as having the most promising UV disinfecting technology.

Pathogens, including the SARS-CoV-2 virus
are able to spread and be transmitted by air or surface routes. UV light and ozone can disinfect circulating air as well as surfaces that cannot be easily reached by conventional disinfecting sprays or wipes.
As confirmed by Dr. Nardell, UV disinfection has been a proven and validated technology for the disinfection of pathogens in air as well as on surfaces for several decades.
Unlike other UV lights, the Sterile-Bright™ UV light is in the right frequency range to disrupt the oxygen molecule, generating ozone (O3), which is a strong sterilizing agent. This combination of UV light and ozone provides an optimum solution for disinfection of contaminated air and surfaces.
Different UV-C sources with different performance characteristics have been utilized for disinfection. The most common UV-C light sources for disinfection include:
• low vapor pressure mercury UV lamps, which emit UV light at 254 nm
• UV light-emitting diode (UV-LEDs) lamps, which emit UV light at wavelengths between 255 and 280 nm
• far-UV-C radiating excimer and micro-plasma lamps, which emit UV light at 200−240 nm.
In contrast, the Sterile-Bright™ UV light emits UV light across most of the UV spectrum, from 180nm to 457nm.7 This is one of several key advantages in disinfection that the Sterile-Bright™ UV light product line boasts over these other UV sources. Sterile-Bright™
UV light emits in the UV-A, UV-B, UV-C, and VUV ranges. In the VUV range of 180nm - 200nm, ozone is produced, which has its own germicidal activity, as highlighted in a later section of the paper.
In addition, Sterile-Bright™ has significantly higher power output than conventional fluorescent UV bulbs, which typically range from only 10-watts to 40-watts and therefore require placement near the target to deliver effective UV doses. The efficacy of Sterile-Bright™ is further enhanced by its 360-degree radial UV distribution.
Dr. Sung earned her Ph.D. in physical chemistry at Harvard University under Professor Dudley Herschbach (1986 Nobel Laureate in Chemistry). Dr. Sung was a National Science Pre-Doctoral Fellow as well as a NATO Postdoctoral Fellow at Harvard University. The bulk of Dr. Sung’s career has been in C-level positions at life science companies. She is currently serving as Chief Business Officer of Aegea Biotechnologies, a private company developing next generation molecular diagnostic tests for SARS-CoV-2, and she is passionate about identifying and applying the best science to address the global health pandemic.
