Iron Oxide Nanozyme in Biomedicine

Iron oxide nanoparticles with intrinsic enzymatic properties are considered as iron oxide nanozymes (IONzymes). IONzymes are bridging the gap between nanotechnology and biomedicine. Their catalytic actions mimic those of natural enzymes such as peroxidase and catalase. IONzymes are synthesized chemically and are less expensive than the preparation of natural enzymes. They are stable over a wide range of pH and temperature, an advantage over natural enzymes. In addition to IONzyme’s enzymatic properties, their magnetic properties provide opportunities for developing of bioseparation assays, imaging tools, targeted drug delivery and hyperthermia therapy in the field of biomedicine.
