Understanding the Power of Light to Kill Germs
Over 100 years and millions of dollars in research has already proven that UV and violet blue light is effective at destroying germs. Violet Defense's technology builds on this research and brings a new patented approach that enables UV and violet blue light to be even more effective and adaptable to every day uses.

Key Benefits of Using Light:
Kills rapidly - starting within seconds
Microbial cells cannot develop resistance to this technology
Proven ability to be able to deploy it safely to kill bacteria, mold, fungi, and even viruses
UV light produces electromagnetic energy that can destroy the ability of microorganisms to reproduce and by causing photo-chemical reactions in nucleic acids (DNA & RNA). The ultraviolet energy triggers the formation of specific thymine or cytosine dimers in DNA and uracil dimers in RNA, which causes inactivation of microbes by causing mutations and/or cell death and failure to reproduce.
Violet Defense uses a powerful, broad spectrum light, including germicidal UV-C, UV-B, UV-A, and violet blue. While UV-C is most traditionally referred to as germicidal UV, UV-B wavelengths have been shown to have 15% of the effect of UV-C on certain bacteria. By combining these wavelengths we are maximizing the dosage of the germ-killing light delivered. Broad band UV lamps have also been shown to inhibit photo-reactivation, the process that can result in self-repair of damaged microbes.
UV has been researched for over a hundred years. Learn more in our research compendium about the proven effectiveness of UV light.
GERM-KILLING POWER OF VIOLET-BLUE LIGHT
It was discovered over 100 years ago that violet-blue spectrum of light can be destructive to bacteria. Blue light in the 405nm to 470 nm wavelength inhibits bacterial and fungal growth. The blue light causes photoexcitation of endogenous porphyrins that leads to the generation of reactive oxygen species, which are toxic to bacterial cells.1
THE VIOLET DEFENSE APPROACH
A key difference with our technology is the ability to seamlessly integrate an effective UV system into everyday products, making them self-sterilizing. The scientific principles to accomplish this are deeply rooted in optical and quantum physics, but our technology also required a mastery of chemistry, biology, bio-medicine, electrical and mechanical engineering, as well as computer engineering.
After significant research, development and validation, the appropriate combination of technologies and materials have been identified and are now ready to easily integrate into existing products to allow them to self-sterilize. The breakthrough produced a technology that not only kills all forms of germs/microbes on the product itself, but also the surrounding areas and even within the air and nearby water/fluids.
Violet Defense Technology represents a significant breakthrough in germicidal protection for the world and is protected by an extensive US and international patent portfolio.
