A photosensitizer being used in photodynamic therapy.

A photosensitizer is a molecule that produces a chemical change in another molecule in a photochemical process.[1] Photosensitizers are commonly used in polymer chemistry in reactions such as photopolymerization, photocrosslinking, and photodegradation.[2] Photosensitizers generally act by absorbing energy electromagnetic radiation in the form of ultraviolet or visible light and transferring it to adjacent molecules.
