Magnetic Iron Oxide Nanospheres

Product Overview
Magnetic iron oxide nanospheres are superparamagnetic materials modified with citric acid. They exhibit excellent magnetism, dispersibility, and stability, making them ideal for a variety of biomedical applications. These nanospheres are widely used in magnetic resonance imaging (MRI) for contrast enhancement, magnetic nanoparticle-based drug delivery, and targeted therapy. By applying an external magnetic field, the magnetic nanoparticles can precisely target disease sites, minimizing side effects in drug delivery and improving therapeutic outcomes.

Key Features

• Excellent Magnetism: Superparamagnetic, enabling rapid magnetization and demagnetization under an external magnetic field.
• Good Dispersibility and Stability: Citric acid-modified Fe₃O₄ nanospheres offer excellent dispersibility and chemical stability, making them suitable for a range of media.
• Enhanced MRI Contrast: Effective as an MRI contrast agent, enhancing image clarity to aid in accurate tissue and lesion detection.
• Targeted Drug Delivery: As drug carriers, these nanospheres reduce the side effects on normal tissues by precisely targeting disease sites via external magnetic fields, improving therapeutic efficacy.

Applications

• Biomolecule Separation: Used in molecular biology research for biomolecule separation and purification.
• Magnetic Resonance Imaging (MRI): Acts as a contrast agent to improve image clarity, aiding in precise lesion localization and medical imaging analysis.
• Magnetic Nanoparticle Drug Carrier: Facilitates drug delivery and targeted therapy, enhancing treatment outcomes while minimizing side effects.
• Magnetic Hyperthermia and Molecular Imaging: In magnetic hyperthermia, nanoparticles are targeted at tumor sites, where an external magnetic field is applied to heat the particles, helping treat cancerous cells.
