Transmission electron micrographs of lavaged cells at 24 h from rats instilled with Au NP suspensions at a dose of 1 mg/kg body weight. a Macrophage uptake of citrate-coated Au NPs and b albumin-coated Au NPs. Micrographs in 6A and 6B insets are higher magnification of the areas shown. c Morphometric analysis of NP uptake. Macrophage uptake was scored similarly as described in Fig. 3. No significant difference in macrophage uptake of NPs (n = 185, citrate-coated Au NPs, n = 191, albumin-coated Au NPs) was found. Data are mean ± SE of % of macrophages (n = 3 rats per NP)
