Figure 5From: Magnetic resonance imaging of glioma with novel APTS-coated superparamagnetic iron oxide nanoparticlesOptical microscopic images of C6 glioma cells. Prussian blue staining of C6 glioma cells that were treated with PBS buffer (a) and those that were treated with acetylated APTS-coated Fe3O4 NPs at a concentration of 10 μg/mL (b), 25 μg/mL (c), and 50 μg/mL (d) (scale bar = 100 μm).Back to article page
