External Magnetic Field‐Induced Targeted Delivery of Highly Sensitive Iron Oxide Nanocubes for MRI of Myocardial Infarction

Magnetic field responsive nanocubes (MFRFs) are synthesized as nanoplatforms for external magnetic field-induced selective targeting of macrophages in the infarcted tissue and magnetic resonance imaging (MRI) monitoring. MFRFs have uniform size, favorable colloidal stability, and high magnetic properties. Under the influence of external magnetic field, MFRFs perform qualitative and quantitative MRI of myocardial infarction.
