Photocatalysts have not only been shown to stop bacteria cells from replicating, but to also decompose the cell itself. The Titanium Dioxide photocatalyst has been found to be more effective than any other antibacterial agent, because the photocatalytic reaction works even when there are cells covering the surface and while the bacteria is still actively propagating. The endotoxin produced at the death of the cell is also expected to be decomposed by the photocatalytic reaction. Titanium Dioxide is a mineral that does not deteriorate and that shows a long-term anti-bacterial effect. Generally speaking, studies of Titanium Dioxide disinfectants show that they are three times stronger than chlorine, and 1.5 times stronger than ozone, with no negative effects on people or animals.
Disclaimer: Though there are a number of peer reviewed papers highlighting the ability of Titanium Dioxide to kill bacteria and viruses, LumActiv is not registered with the US EPA as a pesticide product and therefore can make no antimicrobial claims to the general public.
