What are the Applications of Iron Oxide Nanoparticles?
Iron oxide nanoparticles are used in various fields:
1. Biomedicine: In MRI, they serve as contrast agents due to their superparamagnetic properties. They are also explored for targeted drug delivery systems where drugs are attached to the nanoparticles and directed to specific cells using a magnetic field.
2. Environmental Remediation: They are effective in removing contaminants from water due to their high reactivity and surface area.
3. Catalysis: Their large surface area and active sites make iron oxide nanoparticles efficient catalysts in chemical reactions.
4. Energy Storage: They are used in batteries and supercapacitors, where their high surface area contributes to better performance.
