Once the photosensitizer is exposed to a light with a coordinating spooky array, it's transformed from its ground state into a thrilled singlet state. This enables it to transfer energy to molecular oxygen, creating singlet oxygen and cost-free radicals that moderate mobile toxicity.
The Light
During therapy, an unique light is beamed on the location where the photosensitizer was applied. This light activates the drug and damages cancer cells or precancerous cells that it has actually targeted.
