Representative sequential PCI of O2 gas production. (a) The experimental setup for generating O2 gas. O2 gas bubbles were clearly shown to be continuously produced after H2O2 encountered catalases in the mouse blood. Images were attained following the blood injection at 0 s (b), 1 s (c), 2 s (d), 2.5 s (e), 3 s (f), and 6 s (g), respectively. The pixel size was 9 µm × 9 µm; the exposure time was 8 ms. |
