When the photosensitizer is exposed to a light with a coordinating spooky range, it's transformed from its ground state into an excited singlet state. This allows it to transfer power to molecular oxygen, producing singlet oxygen and free radicals that mediate cellular toxicity.
The Light
During therapy, a special light is radiated on the location where the photosensitizer was used. This light activates the medication and damages cancer cells or precancerous cells that it has targeted.
