Figure 3
Localization of NPs inside the digestive system of the mealworms. (a, e, i) 3D visualizations indicating the locations of three slices which are displayed to the right of those panels; (a) head segment of 1 h-fed mealworm sample, (e) thorax segment of 12 h-fed mealworm sample, (i) abdomen segment of 24 h-fed mealworm sample. The dark (nearly black) regions within the colored circles are identified as NPs; other dark areas result from the shift of biological tissue between the two X-ray scans. Colored circles correspond to: black, buccal cavity; red, pharynx; purple, oesophagus; yellow, crop; green, on surface; blue, midgut; white, encapsulated NPs inside coelom; orange, anterior intestine. |
