Fig. 7: NIR-II fluorescence images of the intestinal tract.

a Real-time monitoring of intestinal peristalsis in living mice gavaged with the 2TT-oC26B NPs (300 μL, 1 mg/mL) using different LP filters (1100 nm LP, 8 ms, 37 mW/cm2; 1200 nm LP, 10 ms, 37 mW/cm2; 1500 nm LP, 75 ms, 110 mW/cm2) at various time points (0.5, 3, 5, 6 h). b Zoom-in images of the two yellow rectangle areas marked in (a) (0.5 and 3 h). Yellow-line dashed rectangles in the images at 5 and 6 h in (a) are zoomed-in and shown in Supplementary Fig. 24. c A cross-sectional fluorescence intensity profile along the red-dashed bar at the top of (b).
