Abstract:
Photodynamic therapy is a nonsurgical, minimally invasive technique that uses a light source to activate light-sensitive drugs or photosensitizers to treat cancer and other diseases. The effect on living organisms caused by light in the presence of a photosensitizer and oxygen is known as the photodynamic effect or photodynamic action.
