Singlet Oxygen

Singlet oxygen is a highly reactive form of oxygen where the electrons are excited to a higher energy state. Unlike regular oxygen (triplet oxygen), singlet oxygen quickly reacts with various molecules, often causing chemical changes. It is involved in processes such as photosensitivity, photodynamic therapy for cancer treatment, and certain environmental reactions. Its reactivity makes it useful for targeted oxidative reactions but also requires careful handling as it can damage cells or materials if not controlled. In summary, singlet oxygen is a energized, reactive form of oxygen that plays important roles in biology, chemistry, and medicine.
