Once the photosensitizer is subjected to a light with a matching spooky range, it's converted from its ground state right into an ecstatic singlet state. This allows it to transfer energy to molecular oxygen, creating singlet oxygen and free radicals that mediate mobile poisoning.
The Light
During treatment, an unique light is beamed on the location where the photosensitizer was applied. This light triggers the medicine and destroys cancer cells or precancerous cells that it has targeted.
