Changes in transfer efficiency of QDs530 linked with different amino acids between tissues in vivo.

0.56 nM of CdTe QDs was administered via oral injection; water was injected as a negative control. (a) Cd ion content in multiple tissues 24 h and 48 h after exposure, determined by the atomic absorption method. (b) Green fluorescence of QDs530 in multiple tissues was measured 24 h after exposure. He, hemolymph; FB, fat body; MT, Malpighian tubule; SG, silk gland; DT, digestive tract. *P < 0.05 and **P < 0.01 indicate significant differences, every tissue sample was collected from 5 larvae and tested three times. Bars are 1 cm.
