A printed superoxide dismutase coated electrode for the study of macrophage oxidative burst

► IJP of SOD does not affect enzymatic activity and produces reproducible electrodes. ► SOD SPE had enhanced selectivity and increased sensitivity over unmodified Pt. ► Continual stimuli of a 2D layer of cells results in sustained oxidative burst. ► Real-time cellular responses can be detected with SPE and microfluidic technology.
