As soon as the photosensitizer is revealed 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 energy to molecular oxygen, creating singlet oxygen and complimentary radicals that mediate mobile poisoning.
The Light
During treatment, an unique light is radiated on the area where the photosensitizer was used. This light triggers the drug and damages cancer cells or precancerous cells that it has actually targeted.

This sets off a series of photochemical reactions that creates responsive oxygen facial beverly hills species (ROS) that damages tumor tissue and eliminate cancer cells.
PDT is usually made use of to treat actinic keratoses and in situ squamous cell cancer (Bowen condition).
