Fig. 5From: The Effect of Superparamagnetic Iron Oxide Nanoparticle Surface Charge on Antigen Cross-Presentation a DCs, which were without γFe O NPs labeling, had round shape and the cytoplasm was uniform. The scale bar represents 1μm. DCs labeled with γFe O /APTS (b) and γFe O /DMSA (c) were imaged by the magnification of 600 nmBack to article page
