International audienceThis review summarises the main electrochemical sensors and biosensors developed for assessing the reactive oxygen (ROS) and nitrogen (RNS) species of interest in clinical and physiological analysis. Among these species, a special attention is focused on sensors for the detection of the highly reactive superoxide radicals O2.−, the very stable hydrogen peroxide H2O2, as well as the well-known RNS nitric oxide (NO.). The different methods adopted for the detection of each species are commented, considering both sensor and biosensors detection strategies
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
