Once the photosensitizer is revealed to a light with a matching spectral array, it's converted from its ground state right into an ecstatic singlet state. This enables it to move energy to molecular oxygen, generating singlet oxygen and cost-free radicals that mediate mobile poisoning.
The Light
During therapy, a special light is beamed on the area where the photosensitizer was used. This light triggers the drug and damages cancer cells or precancerous cells that it has targeted.
