What are Some Applications of Ferromagnetic Nanomaterials?
Ferromagnetic nanomaterials have a wide range of applications, including:
Data Storage: Ferromagnetic nanoparticles are used in high-density magnetic storage media, such as hard drives and magnetic tapes, where they allow for greater storage capacity and faster data access. Biomedical Imaging: Superparamagnetic iron oxide nanoparticles (SPIONs) are commonly used as contrast agents in magnetic resonance imaging (MRI), providing enhanced imaging capabilities. Drug Delivery: Magnetic nanoparticles can be functionalized with therapeutic agents and directed to specific sites in the body using an external magnetic field, improving the efficacy of drug delivery systems. Environmental Remediation: Ferromagnetic nanoparticles can be used to remove contaminants from water and soil through magnetic separation techniques.
