Product Features

For biomolecular coupling, fixation, nanoprobe construction, etc.

Ultra-small size: The size of this type of nanoparticles is usually in the range of 5-10 nm. The ultra-small size helps to improve its diffusion capacity and cellular uptake efficiency in living organisms.

Superparamagnetism: These nanoparticles exhibit superparamagnetic properties with high saturation magnetization, making them suitable for magnetic resonance imaging (MRI) and magnetic hyperthermia therapy (MHT).

Size effect: Fe3O4 nanoparticles with ultra-small particle sizes may exhibit different electronic structures and optical properties from bulk materials. This size effect can be used to regulate the magnetic properties and chemical activity of the material.

Biocompatibility and biodegradability: Fe3O4 is a material with good biocompatibility and can be metabolized and degraded by living organisms, which makes ultra-small Fe3O4 nanoparticles have potential application value in the biomedical field.

Application Fields

Agnetic resonance imaging (MRI) contrast agent: Due to its superparamagnetism, Fe3O4 nanoparticles can be used as a T2 contrast agent for MRI, reducing the relaxation time of surrounding protons and improving the clarity and accuracy of imaging. Surface modification can improve the biocompatibility and tumor targeting performance of Fe3O4 nanoparticles, ultimately improving MRI imaging signals and therapeutic effects.

Magnetic hyperthermia therapy (MHT): Fe3O4 nanoparticles can generate local high temperatures under the action of an external alternating magnetic field and are used for magnetic hyperthermia therapy to treat tumors. Through surface modification, Fe3O4 nanoparticles can enhance their accumulation inside tumors, thereby improving the effect of magnetothermal therapy.

Drug delivery system: Fe3O4 nanoparticles can be used as drug carriers, enriched in tumor tissues through the EPR effect, and improve the targeted transport efficiency of drugs.

Multimodal imaging and tumor collaborative therapy: Fe3O4 nanoparticles and their derived composite nanomaterials have attracted widespread attention in multimodal imaging and tumor collaborative therapy. Fe3O4 nanoparticles of different sizes can be obtained through different preparation methods, and modification on their surface can improve biocompatibility and tumor targeting performance.
