Marek Scholz, Charles University, and Manjul Shah, Princeton Instruments

A new experimental setup allows researchers to monitor a highly reactive species of molecular oxygen that plays an important role in a wide range of biological processes. Oxygen is one of the most important molecules in maintaining life, as well as in mechanisms by which life is extinguished and materials destroyed. For several decades, researchers have been intrigued by the physical and chemical properties of molecular oxygen’s lowest excited state, singlet oxygen (1O2). In particular, singlet oxygen has a unique reactivity that can result in polymer degradation or the death of...Read full article
