Biodistribution of NDs in the fat body following the exposure of T. molitor to FITC-NDs. (A–C) Control fat body; (D–G) NDs are visible in the fat body cells of insects exposed to 5 µg of FITC-ND for 1 day. The red circles show the colocalization of FITC signals and black dots. Black dots indicate, in the transmitted light, FITC-ND conglomerates.
