Deciphering the catalytic mechanism of superoxide dismutase activity of carbon dot nanozyme
Nature Communications, 2023 Superoxide dismutase (SOD) nanozymes show mitigating effect on oxidative stress-related diseases, but are limited by their modest activity. Here, the authors report a carbon dot SOD nanozyme with catalytic activity matching natural enzymes and unveil its

Superoxide Anion Chemistry—Its Role at the Core of the Innate Immunity
International Journal of Molecular Sciences, 2023 Classically, superoxide anion O2•− and reactive oxygen species ROS play a dual role. At the physiological balance level, they are a by-product of O2 reduction, necessary for cell signalling, and at the pathological level they are considered harmful, as ...

Superoxide Radicals in the Execution of Cell Death
Antioxidants, 2022 Superoxide is a primary oxygen radical that is produced when an oxygen molecule receives one electron. Superoxide dismutase (SOD) plays a primary role in the cellular defense against an oxidative insult by ROS. However, the resulting hydrogen peroxide is

Superoxide dismutase nanozymes: an emerging star for anti-oxidation.
Journal of materials chemistry. B, 2021 Superoxide dismutases (SODs) are a group of metalloenzymes that catalyze the dismutation of superoxide radicals (O2˙-) into hydrogen peroxide (H2O2) and oxygen (O2). As the first line of defense against reactive oxygen species (ROS)-mediated damage, SODs

Superoxide dismutases: Dual roles in controlling ROS damage and regulating ROS signaling
Journal of Cell Biology, 2018 Superoxide dismutases (SODs) are universal enzymes of organisms that live in the presence of oxygen. They catalyze the conversion of superoxide into oxygen and hydrogen peroxide.

Enhanced Superoxide Generation on Defective Surfaces for Selective Photooxidation.
Journal of the American Chemical Society, 2019 Photocatalytic selective oxidation reactions hold great promise for the design of high-value-added organic intermediates, but many of these reactions suffer from low conversion efficiency and selectivity due to uncontrollable oxidation processes. In view

Superoxide Dismutases and Superoxide Reductases
Chemical Reviews, 2014 Superoxide, O2•–, is formed in all living organisms that come in contact with air, and, depending upon its biological context, it may act as a signaling agent, a toxic species, or a harmless intermediate that decomposes spontaneously.
