Determination of the sublethal dose and intracellular content of AuNP exposure on macrophages. Cell viability (n = 3) stimulated by a series of concentrations (0, 1, 2, 5, 10, and 20 μg/mL) of A 5 nm and B 50 nm AuNPs with different coatings for 24 h. Morphology of cells exposed to C 5 nm and D 50 nm AuNPs (5 and 20 μg/mL) with different coatings for 24 h. The scale bar is 30 μm. E The intracellular content of AuNPs (mean ± SD, n = 3) with different diameters and coatings analyzed by ICP-MS
