The production of excessive superoxide anions (O 2•-) in living cells will induce oxidative
stress, leading to mitochondrial dysfunction and further activating pathogenic factors …

The ubiquity and importance of ROS and RNS in cellular signaling, disease development,
and death give rise to an outstanding interest in their detection and quantification. Among …

The dynamic balance of the redox system in living organisms can be disrupted by excessive
superoxide anion (O 2•−), which would lead to oxidative stress and induce a variety of …

In this study, we describe a new and straightforward method of electrode modification for
introducing intrinsic defects into hierarchically porous carbon (D-HPC), and we use this …

It is of great significance to realize the detection of trace amounts of superoxide anions (O
2•−) in biological systems due to the connection between the concentration of O 2•− and …
