Abstract
Iron oxide (IO) nanoparticles (NPs) have gained significant attention in the field of biomedicine, particularly in drug targeting and cancer therapy. Their potential in magnetic drug targeting (MDT) and ferroptosis-based cancer therapy is highly promising. IO NPs serve as an effective drug delivery system (DDS), utilizing external magnetic fields (EMFs) to target cancer cells while minimizing damage to healthy organs. Additionally, IO NPs can generate reactive oxygen species (ROS) and induce ferroptosis, resulting in cytotoxic effects on cancer cells. This article explores how IO NPs can potentially revolutionize cancer research, focusing on their applications in MDT and ferroptosis-based therapy.
