When the photosensitizer is revealed to a light with a matching spectral range, it's converted from its ground state right into a thrilled singlet state. This enables it to move energy to molecular oxygen, generating singlet oxygen and cost-free radicals that mediate cellular poisoning.
The Light
During therapy, a special light is radiated on the area where the photosensitizer was applied. This light turns on the medication and damages cancer cells or precancerous cells that it has actually targeted.
