Figure 11From: Magnetic resonance imaging of glioma with novel APTS-coated superparamagnetic iron oxide nanoparticlesPrussian blue staining of C6 glioma xenografts on the 14th day. (a) The tumor model was labeled with 25 μg/mL of acetylated APTS-coated Fe3O4 NPs (scale bar = 200 μm). (b) A negative PBS control without particle labeling (scale bar = 200 μm).Back to article page
