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, creating singlet oxygen and totally free radicals that mediate mobile poisoning.
The Light
During therapy, an unique light is shined on the location where the photosensitizer was applied. This light activates the medicine and ruins cancer cells or precancerous cells that it has targeted.

It is soaked up by the growth cells and turned on when exposed to light of a certain wavelength. This triggers a series of photochemical reactions that produces responsive oxygen species (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). It can additionally be used to deal with various other kinds of skin cancer cells, including shallow basic cell carcinoma. It can be utilized alone or with other treatments, such as surgical procedure or radiation.
