Fig. 5From: Surface chemistry governs the sub-organ transfer, clearance and toxicity of functional gold nanoparticles in the liver and kidneyTEM images of mouse liver at 1Â h after i.v. injection of functionalized GNPs. PEG-GNPs were deposited in the cytosol of KCs (a1) and Disse space (a2); CS-GNPs were deposited in the cytosol of KCs (b1) and cytosol of ECs (b2); PEI-GNPs were deposited in the cytosol of KCs (c1), space of Disse (c2). KC: Kupffer cells; EC: endothelial cells. Clusters of GNPs were indicated by red arrowsBack to article page
