AquiSense Scientist Publishes Whitepaper on Far UV-C
Our Head of Application Science, Rich Simons, along with coauthors Ernest R. Blatchley III, and Karl G. Linden, recently published a whitepaper in the July 2020 issue of UV Solutions Magazine where they discuss the application of 200 -225 nm, of far UV-C for disinfection.
AquiSense Technologies is a leading UV-C LED product manufacturer, creating a range of laboratory equipment in addition to product lines for air, surface, or water treatment. We operate as a business to business company, supplying our component products to OEMs and distributors who work in the manufacturing space. We were founded on the principle of innovation, and though our core focus is on UV-C LEDs we actively engage with UV technologies across the full spectrum of maturity.
The COVID-19 pandemic has caused a surge in interest in disinfection technologies such as UV, with well-established approaches (such as UV-C LEDs) rightfully finding a wide range of applications; however, earlier-stage technologies such as ‘far UV-C’ have also garnered attention. Far UV-C is a high-energy subsection of the UV-C spectrum and its proponents claim disinfection capabilities like conventional UV-C sources. This is a young field of research with a promising outlook, though the evidence base is not yet sufficient for us to consider far UV-C sources as safe for human exposure, and we do not recommend or endorse systems designed to that intent. UV-C LEDs operating in the far UV-C range are not commercially viable for disinfection applications, existing in laboratories and niche sensing applications only; the most common far UV-C sources are KrCl* excimer plasma discharge lamps.
AquiSense Technologies will continue to engage with academic, industrial, and regulatory partners to build understanding of this technology and shape its development towards safe and effective application. We continually analyze the performance of UV sources from numerous manufacturers in order to create the best possible UV disinfection products.

UV Dose Response Research Completed on COVID-19, highlighted by AquiSense Technologies
UV-C LED lamps were used to prove disinfection of COVID-19 by independent researchers at the University of Miyazaki, Japan. This study provides data on the disinfection possibilities of UV to aid the fight against COVID-19.
AquiSense Technologies, the world leader in ultraviolet (UV) LED disinfection systems, is pleased to share the latest research conducted on SARS-CoV-2 (the virus which causes COVID-19) with UV-C LED technology. University of Miyazaki, Japan, conducted the research on SARS-CoV-2 isolated from the Diamond Princess cruise ship, which saw numerous cases early in the pandemic. Researchers exposed the virus to radiation from Nikkiso UV-C LEDs (280 nm peak) to determine a UV Dose response curve.
“This work certainly bolsters the case for the use of UV-C LEDs for societal benefit against SARS-CoV-2. Considering the large number of research projects underway exploring the efficacy of UV-C on the virus, we can expect the supporting body of evidence to only increase,” said AquiSense CTO, Jennifer Pagan, Ph.D.
The study used an infectivity assay on Vero cells to measure inactivation the SARS-CoV-2 under UV-C LED irradiation. By varying exposure time for each sample the researchers were able to generate a series of datapoints known as a ‘dose response curve’; data such as these are used throughout the UV industry, allowing system designers to match a target UV exposure to a desired degree of inactivation. This study is the first demonstration of a UV Dose response curve for SARS-CoV-2.
Analysis of these data gives a D90 value (the UV Dose required to achieve a 90% reduction) in the 4.2 – 5.3 mJ cm-2 range, indicating that SARS-CoV-2 may be more susceptible to UV exposure than other common viruses such as norovirus. However, a low starting concentration of the virus limited the maximum inactivation that could be measured to 3.3-log (99.95%) and may have resulted in an effect known as ‘tailing’. Both features limit conclusions which can be drawn from the data.
Rich Simons, Ph.D, Head of Application Science at AquiSense added “The more we learn about the way this virus behaves the better we can design systems to combat it effectively. This study is certainly not the end of discussion on UV as a tool for SARS-CoV-2 inactivation but adds a useful datapoint to our ongoing analysis and gives us confidence that we’re on the right track.”

IUVA Discourage the Use of UV Light on the Human Body to Disinfect Against the Coronavirus
Recent reports suggest that ultraviolet (UV) light can be used on the human body to disinfect against the coronavirus. The International Ultraviolet Association (IUVA) are educational and advocacy organizations consisting of UV equipment vendors, scientists, engineers, consultants, and members of the medical profession. We would like to inform the public that there are no protocols to advise or to permit the safe use of UV light directly on the human body at the wavelengths and exposures proven to efficiently kill viruses such as SARS-CoV-2. UV light under the conditions known to kill such viruses are also known to cause severe skin burns, skin cancer, and eye damage. We strongly recommend that anyone using UV light to disinfect medical equipment, surfaces, or air in the context of COVID-19, applications that are supported by sound scientific evidence, follow all recommended health and safety precautions and to avoid direct exposure of the body to the UV light.

UV Dose Response Tool - PearlLab Beam™ Used in Hemoglobin Research
Animal-derived products as starting material for pharmaceutical or biotechnological products represent a considerable risk for viral contamination. Despite a careful source selection and traceability, the risk of transmitting a viral disease remains. Therefore, a viral inactivation step in the manufacturing process is essential for meeting the current quality and safety requirements. Research proved that Act-O2-Hem loses its functionality with traditional viral inactivation methods like Gamma irradiation, pH treatment, and heat inactivation. Therefore, an alternative, safe, and simple viral inactivation method was needed that did not affect Act-O2-Hem.
UV-C light is often used in water, air, and surface disinfection. UV-C light can also disinfect animal-derived products. Virus inactivation experiments were performed using the PearlLab Beam and results showed that UV-C light disinfected the Act-O2-Hem while not significantly affecting the functionality of Act-O2-Hem.
