Photodynamic therapy (PDT) is a medical treatment that utilizes photosensitizing agents, light, and oxygen to induce cell death. It is primarily used to treat various cancers and certain non-malignant conditions. The process involves the administration of a photosensitizer, which accumulates in the target cells. Upon irradiation with a specific wavelength of light, the photosensitizer produces reactive oxygen species (ROS) that can destroy the diseased cells.
