As soon as 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 energy to molecular oxygen, generating singlet oxygen and cost-free radicals that moderate cellular toxicity.
The Light
