Why can’t cellular repair mechanisms overcome UV-C damage?
The damage caused by Xenex’s Full Spectrum™ UV-C stops the DNA repair mechanisms for most pathogens in less than 5 minutes. In addition, Pulsed Xenon produces higher energy wavelengths than other UV sources which results in damage to structures in the cell, including ruptured cell walls.

What is the effectiveness of Xenex against endospores like C. diff and bacillus strains?
The UV-C intensity of Xenex LightStrike® Robots allows for the deactivation of endospores in 5 minutes! This has been demonstrated in lab studies, hospital environment studies, and validated in outcome studies proving reductions of C. diff rates reported by several hospitals utilizing Xenex.

How long does the disinfection last?
After disinfection, the room will remain at very low microbial load until new pathogens enter the room from a visitor, patient, care provider or the air handling system. A hospital does not need to repeat the Xenex decontamination procedure in a properly cleaned and disinfected room as long as there has been no re-contamination.

Do shading or shadows in the room impact Xenex efficacy?
Third-party studies have shown that, "... pathogen concentration, organic load, and shading from the direct field of radiation did not" reduce Xenex's efficacy (Donskey, 2015). However, we recommend running the Robot in multiple positions in a room to maximize the number of surfaces that are directly exposed to Full Spectrum™ UV-C and to minimize dependence on surface reflectivity that varies from room to room and surface to surface. Historical UV-C technologies that were used in only one position in the room have not achieved the multiple C.diff and MRSA rate reductions that hospitals using Xenex have reported in peer-reviewed journals.

Is UV-C harmful?
You might be familiar with UV-A and UV-B, the potentially harmful wavelengths in sunlight. Xenex uses UV-C, which cannot penetrate through glass, plastic, clothing, or the top layer of your skin. While prolonged UV-C exposure can be harmful to eyes and skin, the Xenex Robot employs several safety mechanisms to prevent accidental exposure.

What if someone walks in while the device is operating?
The LightStrike Robot should only operate in an unoccupied room. Although brief exposure to the light is not a threat, the triple-sensor motion detector will stop the pulses in milliseconds if the room door is opened – before anyone can enter the room. An external “stop” button provides an immediate shutdown should anyone need to re-enter the room before a cycle is complete.

Can I look at the device through a window while it is operating?
Yes. The UV-C waves cannot penetrate through the glass. Therefore, it is safe to be on the other side of a window or wall.

Is Xenex publicly traded? What is your stock ticker symbol?
Xenex is privately held, and has received investment from several highly-regarded technology funds, including Battery Ventures, Targeted Technology Fund II, RK Ventures, and Brandon Point Industries Limited (Brandon Point).
