Effect of Fe₃O₄ Nanoparticles on Skin Tumor Cells and Dermal Fibroblasts

Figure 1

(a) Cell viability of fibroblasts. Cells were incubated with Fe₃O₄ nanoparticles. The percentage of living cells was measured after 72 h. . (b) Cellular uptake of Fe₃O₄ nanoparticles. Fibroblasts (HDF) (A, B) and SCL-1 tumor cells (C, D) were untreated (A, C) or incubated (B, D) with 350 μM Fe₃O₄ nanoparticles for 24 h to determine the cellular uptake of the nanoparticles.
