The antimicrobial action of singlet oxygen from photosensitive particles is well documented.* Below, is an explanation of how photosensitive dyes in the presence of light, create reactive oxygen species, (ROS) including singlet oxygen. Reactive oxygen species (ROS) are generated during mitochondrial oxidative metabolism as well as in cellular response to xenobiotics, cytokines, and bacterial invasion.
The singlet oxygen technology within PurePurge™ provides a safe, proven, self-renewing, and sustainable source of disinfection. PurePurge™ has perfected the technique of producing large quantities of singlet oxygen in an commercially viable manner, by creating a self renewing, non-depleting source of singlet oxygen.
Singlet oxygen, systematically named dioxygen(singlet) and dioxidene, is a gaseous inorganic chemical with the formula O=O (also written as 1`{`O 2`}` or 1 O 2), which is in a quantum state where all electrons are spin paired. It is kinetically unstable at ambient temperature, however the rate of decay is slow.
When a photo-sensitizing dye like PurePurge™ absorbs light, the molecules become excited into a higher energy state. The photosensitive dye then transfers this energy to the oxygen molecules around it.
This energy transforms “ground-state” oxygen molecules into ROS (reactive oxygen species) molecules called Singlet Oxygen.
These newly formed Singlet Oxygen molecules subsequently destroy microbes that they encounter through radical oxidation. Singlet oxygen has no specific target within a microbe – it is completely nonselective.
Resistance to microbicides usually develops either when they are used incorrectly, or where the microbicide targets only a specific part of the organism. Singlet Oxygen molecules created by PurePurge™ oxidizes the entire cell instead of poisoning or puncturing a specific site.
