Abstract
Background:
Biomedical applications of Magnetic Nanoparticles (MNPs) are creating a major impact on
disease diagnosis and nanomedicine or a combined platform called theranostics. A significant progress has been
made to engineer novel and hybrid MNPs for their multifunctional modalities such as imaging, biosensors, chemotherapeutic
or photothermal and antimicrobial agents. MNPs are successfully applied in biomedical applications
due to their unique and tunable properties such as superparamagnetism, stability, and biocompatibility. Approval of
ferumoxytol (feraheme) for MRI and the fact that several Superparamagnetic Iron Oxide Nanoparticles (SPIONs) are
currently undergoing clinical trials have paved a path for future MNPs formulations. Intensive research is being
carried out in designing and developing novel nanohybrids for multiple applications in nanomedicine.
Objective:
The objective of the present review is to summarize recent developments of MNPs in imaging modalities
like MRI, CT, PET and PA, biosensors and nanomedicine including their role in targeting and drug delivery. Relevant
theory and examples of the use of MNPs in these applications have been cited and discussed to create a thorough
understanding of the developments in this field.
Conclusion:
MNPs have found widespread use as contrast agents in imaging modalities, as tools for bio-sensing, and
as therapeutic and theranostics agents. Multiple formulations of MNPs are in clinical testing and may be accepted in
clinical settings in near future.
