Electrochemical Sensor and Biosensor Strategies for ROS/RNS Detection in Biological Systems
Résumé
This 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.
