Ultrastructural imaging of nanoparticles in the extracellular space. A) image showing three confluent parenchymatic cells with a triangle shaped extracellular region between them. The parenchymatic cells do not show traces of presence of nanoparticles. B) High magnification of the extracellular channel shown in (A) displaying nanoparticle aggregates. Bar in A = 10 μm; B = 200 nm
