Once the photosensitizer is revealed to a light with a coordinating spectral array, it's transformed from its ground state into an excited singlet state. This allows it to move energy to molecular oxygen, generating singlet oxygen and cost-free radicals that mediate cellular poisoning.
The Light
Throughout treatment, an unique light is beamed on the area where the photosensitizer was applied. This light turns on the medication and destroys cancer cells or precancerous cells that it has actually targeted.
