An example of the use of TEM images to determine the accumulation of NM in Daphnia guts and potential translocation. Uptake and localisation of (A) freshly dispersed PVP-coated Ag NMs in HH combo medium showing microvilli interactions, (B) freshly dispersed PVP-coated Ag NMs in HH combo found in the gut lumen space; and (C) freshly dispersed uncoated TiO₂ NMs in HH combo, showing evidence of NM translocation in the bush border.
