As soon as the photosensitizer is revealed to a light with a coordinating spooky variety, it's transformed from its ground state into a thrilled singlet state. This enables it to transfer energy to molecular oxygen, generating singlet oxygen and free radicals that mediate mobile poisoning.
The Light
Throughout therapy, an unique light is radiated on the area where the photosensitizer was applied. This light activates the drug and destroys cancer cells or precancerous cells that it has targeted.
