Fig. 1

Influence of the dispersed oxygen-sensitive nanoparticle concentration on the measured signal intensity. Shown are the mean values of the determined signal intensities with corresponding standard deviations of 20 independent measurements. The black dashed line indicates the recommended signal intensity (100 mV) for reliable dissolved oxygen tension (DOT) measurements. Measurement conditions: Non-inoculated YM medium with varying oxygen-sensitive nanoparticle concentrations, 250 mL shake flask, 30 °C, n = 200 rpm, VL = 20 mL, shaking diameter d0 = 50 mm
