Pulsed White Light as a Tool for DisinfectionPublic
Downloadable Contentopen in viewer
Pulsed White Light is an effective tool for disinfection when used with photosensitizers. Here the possibility of PWL alone being an effective tool for use against Bacillus subtilis spores was explored. Previous work was reviewed, and it was determined that PWL technology is not effective against B. subtilis spores without the use of a photosensitizer, refuting previous claims. However, it appears that using pulsed sources of ultraviolet light can be effective at killing over 99% of spores at high concentrations.
