In Vitro Safety Evaluation and In Vivo Imaging Studies of Superparamagnetic Iron Oxide Nanoparticles through Biomimetic Modification

<div>HepG2 cells were exposed to 0 (a), 2 (b), 5 (c), and 10 <i>μ</i>g/mL (d) SPION, PDA-SPION, and c (RGDyK)-PDA-SPION magnetic nanoparticles for 24 hours. Enrichment results of magnetic nanoparticles in HepG2 cells were detected.</div>
