Magnetic Mesoporous Silica Nanoparticles (MMSNs)

Product Overview
Magnetic Mesoporous Silica Nanoparticles (MMSNs) are multifunctional nanocomposite materials that combine magnetic and mesoporous structures. The core consists of superparamagnetic iron oxide (Fe₃O₄) nanoparticles, while the outer shell is composed of mesoporous silica with high surface area, uniform pore structure, and excellent chemical stability. This unique structure enables MMSNs to have broad application potential in fields such as drug delivery, magnetic resonance imaging (MRI), magnetic hyperthermia, and catalysis.

Product Features

• Magnetic Responsiveness: The magnetic nanoparticles provide the material with the ability to be manipulated and separated using an external magnetic field, making MMSNs suitable for various biomedical and environmental engineering applications.
• Mesoporous Silica Matrix: The mesoporous silica shell offers a stable platform with a high surface area and pore sizes ranging from 2-50 nm, enhancing molecular adsorption, diffusion, and catalytic reactions.
• High Surface Area: The mesoporous structure significantly increases the surface area, boosting catalytic efficiency and material adsorption capacity.
• Chemical Stability & Biocompatibility: The silica matrix exhibits excellent chemical stability and biocompatibility, making MMSNs suitable for biomedical applications.
• Multifunctionality: Surface modification or post-treatment allows for the introduction of various functional groups, enabling MMSNs to cater to specific applications such as molecular adsorption, catalysis, or targeted drug release.

Applications

• Drug Delivery Systems: MMSNs can serve as efficient drug carriers for targeted drug delivery and controlled release, improving therapeutic effects while reducing side effects. They are suitable for both hydrophilic and hydrophobic drugs.
• MRI Contrast Agents: Due to their superparamagnetic properties, MMSNs can be used as MRI contrast agents to enhance imaging signals, aiding in early disease diagnosis.
• Magnetic Hyperthermia: In the presence of an alternating magnetic field, the magnetic nanoparticles generate heat, which can be utilized for cancer treatment. When combined with drug delivery, MMSNs enhance therapeutic efficacy.
• Catalysis Applications: The high surface area and unique pore structure make MMSNs suitable as catalysts or catalyst supports, with applications in various chemical reactions.
