A representative MTGB tumor with histologic sections taken five minutes after mNP injection. These H&E and Prussian blue photomicrographs demonstrate regional heterogeneity in mNP distribution. The 110 nm diameter mNP were injected in four tissue quadrants, with a total of 7.5 mg of Fe per cm3 tumor, five minutes prior to tumor removal and processing. Regions indicated on the low magnification images are shown in the high magnification images. H&E and Prussian blue. A&B at 10× magnification, C,D,E, and F at 100× magnification.
