Biodistribution of NDs in Malpighian tubule cells following exposure of T. molitor to FITC-NDs. (A–C) Control cells of the Malpighian tubules. (D–F) There was no colocalization of FITC signals and black dots indicating ND accumulation in the Malpighian tubule cells of insects exposed to 5 µg of FITC-ND for 1 day.
