Reactive Oxygen Species Generation via Porphyrin Photosensitization (ROS Generation via Porphyrin Photosensitization)

Reactive oxygen species generation via porphyrin photosensitization is a well-established biochemical process central to modern photodynamic therapies that leverage tunable organic chromophores for controlled oxidative damage within targeted tissues. It involves the absorption of light by porphyrin-based photosensitizers, which then transfer energy to molecular oxygen, producing cytotoxic ROS such as singlet oxygen, superoxide, peroxyl, and hydroxyl radicals. These ROS induce cell death through apoptosis, necrosis, or autophagy, making it a valuable tool for cancer therapy and antimicrobial treatments.
