Characterization of the magnetic nanoparticles that we used for blood occlusion. The transmission electron microscopy images were taken by a transmission electron microscope. a, b Images of MPs with transmission electrical microscopy. 1 mg/ml (a) and 0.1 mg/ml (b), (a’) inset from (a). c. The diameter of MPs (nanoclusters) was obtained with a particle size analyzer
