What Types of Nanomaterials Are Used for Antioxidant Applications?
Several types of nanomaterials exhibit antioxidant properties:
- Metallic Nanoparticles: Gold, silver, and platinum nanoparticles have shown intrinsic antioxidant properties. They can also act as carriers for traditional antioxidants. - Carbon-Based Nanomaterials: Fullerenes, carbon nanotubes, and graphene oxide possess antioxidant capabilities due to their unique electronic structures. - Polymeric Nanoparticles: These can be loaded with antioxidant molecules and designed for controlled release. Polylactic acid (PLA) and polyethylene glycol (PEG) are commonly used polymers. - Lipid-Based Nanoparticles: Liposomes and solid lipid nanoparticles can encapsulate antioxidants, enhancing their stability and bioavailability.
