The absorbed SPIO nanoparticles mainly dispersed inside the perinuclear lysosomes (white arrows), and the phenomenon in the PEG/PEI-modified SPIO-labeling group (a) was more obvious than the PEG/PVP-modified SPIO-labeling group (b); the intracellular organelle structures were complete and not significantly damaged (×30000).
