As soon as the photosensitizer is subjected to a light with a matching spectral array, it's converted from its ground state into a fired up singlet state. This allows it to transfer power to molecular oxygen, producing singlet oxygen and totally free radicals that mediate mobile toxicity.
The Light
During therapy, an unique light is shined on the location where the photosensitizer was used. This light activates the medicine and ruins cancer cells or precancerous cells that it has targeted.

The photosensitizer is supplied into the skin with topical, dental or intravenous administration. It is soaked up by the growth cells and turned on when subjected to light of a details wavelength. This sets off a series of photochemical reactions that produces responsive oxygen types (ROS) that damages tumor tissue and eliminate cancer cells.
PDT is most often made use of to treat actinic keratoses and sitting squamous cell cancer (Bowen illness).
