When the photosensitizer is exposed to a light with a coordinating spooky variety, it's converted from its ground state right into an ecstatic singlet state. This enables it to transfer power to molecular oxygen, producing singlet oxygen and totally free radicals that moderate mobile toxicity.
The Light
Throughout therapy, a special light is shined on the location where the photosensitizer was applied. This light turns on the medication and ruins cancer cells or precancerous cells that it has targeted.

This sets off a sequence of photochemical responses that creates responsive oxygen species (ROS) that damages tumor tissue and eliminate cancer cells.
PDT is usually made use of to treat actinic keratoses and sitting squamous cell carcinoma (Bowen illness).
