Preparation of Uniform and Size Tunable Iron Oxide Magnetic Nanocrystals
Iron oxide magnetic nanocrystals (MNCs) are nanocrystals that exhibit magnetic properties. They are currently being tested for various applications such as magnetic seals, cell sorting, magnetic resonance imaging (MRI), gene therapy, etc. Iron oxide nanocrystals hold d promise for various applications because they are maneuverable with remote magnetic fields. In biomedical applications, MNCs can be coated with various marker molecules to make them selectively adhere to target analytes. The MNCs can be used to deliver anti-cancer drugs or radioactive materials directly to a specific site such as tumor. These particles can also be designed to attach to cancerous tissue and then heated with a remote alternating magnetic field that selectively kill cancer cells in a process called magnetic hyperthermia.
