Synthesis of acid-stabilized iron oxide nanoparticles and comparison for targeting atherosclerotic plaques: Evaluation by MRI, quantitative MPS, and TEM alternative to ambiguous Prussian blue iron staining

In apoE−/− mice, VSOPs were the best anionic iron oxide particles for imaging atherosclerotic plaques. MPS allowed for quantification of superparamagnetic nanoparticles in such small specimens.134
