Fig. 2

a–c shows the degradation of the discs in HBSS and d–f in DMEM. The images were acquired at time 0 min (a, d), 60 min (b, e) and 120 min (c, f) after adding the respective solution containing O2-sensitive nanoparticles. All sample types showed the development of gas bubbles (arrows) over the measured duration. The image contrast was adjusted for better visibility.
