Figure 5

Prussian blue staining. (a) Control cells: no iron oxide nanoparticle incubation (potassium ferrocyanide solution also present); (b) After 17 hours of incubation with iron oxide nanoparticles ([Fe] = 2 mM), potassium ferrocyanide solution was added. A blue coloring appears in (b) and highlights the presence of iron oxide nanoparticles.
