Photodynamic Therapy (PDT) leads to what kind of reaction?

Photodynamic Therapy (PDT) involves the use of photosensitizing agents that, when exposed to light of a specific wavelength, produce reactive oxygen species (ROS) through a series of chemical reactions. This results in cellular damage and destruction of targeted tissues, particularly in cancerous or diseased cells. The process primarily relies on the interaction of the photosensitizer and the light to initiate a chemical reaction, leading to the destruction of abnormal cells. This mechanism is fundamental to the efficacy of PDT in treating various medical conditions, particularly in oncology and dermatology. The ability of PDT to selectively target and destroy unwanted cells while minimizing damage to surrounding healthy tissue is key to its therapeutic potential.
