- Targeted Drug Delivery: Magnetic nanoparticles can be engineered to carry therapeutic agents. By guiding these nanoparticles to specific locations in the body using magnetic fields, drugs can be delivered directly to the site of disease, minimizing side effects and improving treatment efficacy. - Hyperthermia Treatment: Magnetic nanoparticles can be used for cancer treatment by heating them with an alternating magnetic field, which destroys cancer cells without harming the surrounding healthy tissue. - Magnetic Resonance Imaging (MRI): Magnetic nanoparticles enhance the contrast in MRI scans, making it easier to diagnose and monitor diseases. - Tissue Engineering: Magnetic guidance can be used to arrange cells or biomaterials in specific patterns, aiding the development of complex tissue structures.
