Real-time monitoring of cellular superoxide anion release in THP-1 cells using a catalytically amplified superoxide dismutase–based microbiosensor

Reactive oxygen species (ROS) including the superoxide anion (O 2 •− ) are typically studied in cell cultures using fluorescent dyes, which provide only discrete single-point measurements. These methods lack the capabilities for assessing O 2 •− kinetics and release in a quantitative manner over lon...
