When the photosensitizer is exposed to a light with a matching spooky variety, it's converted from its ground state right into an ecstatic singlet state. This enables it to move power to molecular oxygen, generating singlet oxygen and free radicals that moderate cellular poisoning.
The Light
Throughout 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.
