Superparamagnetic Iron Oxide Nanoparticles for Cancer Therapy and MRI Imaging
This research community develops superparamagnetic iron oxide nanoparticles (SPIONs) and related ferrites to treat cancer through magnetic hyperthermia and targeted drug delivery, while simultaneously using them as contrast agents for magnetic resonance imaging.
The work centers on the synthesis, surface functionalization, and characterization of iron oxide (Fe3O4) and cobalt ferrite nanoparticles. Recurring themes include the engineering of core-shell structures to enhance magnetic properties and biocompatibility. Applications are heavily concentrated in biomedical contexts, specifically for heating tumor cells via alternating magnetic fields, improving MRI contrast resolution, and facilitating the targeted transport of therapeutic agents to cancer cells. While the primary focus is oncology, a secondary strand of research applies these magnetic particles to environmental remediation, such as wastewater treatment, and to catalytic processes.
Iron research accounts for the largest share of this community's output, representing 2.9% of all tracked iron research, with 11,872 papers. Cobalt and silicon follow as secondary elements, contributing 1,266 and 951 papers respectively.
The community comprises 19,826 papers, published predominantly in the Journal of Magnetism and Magnetic Materials, International Journal of Nanomedicine, and Nanoscale.
Recent work continues to focus on the clinical translation of SPIONs, with specific attention to their use in precision cancer theranostics, the optimization of magnetic properties for improved biomedical performance, and the assessment of their toxicity and biosafety profiles.
