Figure 6. TEM images of n-ZnO suspensions (10 µg/ml in ASW) (A) and their intracellular localisation in mussel hemocytes (B–C).

Hemocytes were incubated with n-ZnO (10 µg/ml in ASW) for different periods of time as described in Methods. B) n-ZnO (30 min). Squares indicate the presence of n-sized ZnO particles within multivesicular endosomes (end). C) n-ZnO (60 min). An apoptotic cell is shown.
