When the photosensitizer is exposed to a light with a coordinating spooky variety, it's converted from its ground state right into an ecstatic singlet state. This enables it to move power to molecular oxygen, producing singlet oxygen and totally free radicals that mediate mobile poisoning.
The Light
During therapy, an unique light is shined on the location where the photosensitizer was applied. This light activates the medicine and ruins cancer cells or precancerous cells that it has targeted.
The medicines that are utilized in photodynamic therapy have various absorption buildings and a few of them may take hours to leave normal cells yet stay longer in cancer cells or precancer cells.
