Redox means reduction and oxidation reactions, in which the transfer of electrons, hydrogen atoms, or hydride ions occurs, and plays a pivotal role in biological reactions, such as photosynthesis, cell respiration and so on. Our research group aims to elucidate the mechanisms for bio-related redox reactions, especially for generating and scavenging of reactive oxygen species and related radicals at molecular and quantum levels, using physicochemical techniques.
