The core material of carboxylated dextranModified ferric oxide nanoparticles is ferric oxide, which has superparamagnetic properties and is suitable for magnetic field response applications. The surface is covered with carboxylated dextran, a modification that increases the water solubility and biocompatibility of the nanoparticles while providing carboxyl functional groups that facilitate further chemical modification and coupling of biomolecules.

Product Features
Superparamagnetism: Fe3O4 nanoparticles are superparamagnetic and can be rapidly magnetized and demagnetized under an external magnetic field. They are suitable for magnetic resonance imaging and magnetic hyperthermia. Carboxyl Functionalization: Surface carboxylation provides reactive chemical groups that facilitate covalent binding to drugs, biomolecules, or targeting ligands. Biocompatibility: Modification of carboxylated dextran improves the compatibility of nanoparticles with biological systems and reduces potential toxicity to normal cells. Stability: Modification of carboxylated dextran enhances the stability of nanoparticles in vivo and reduces the risk of aggregation and precipitation.
Application Fields
Magnetic Resonance Imaging (MRI): These nanoparticles can be used as MRI contrast agents to enhance imaging signals. Modification of carboxylated dextran improves its biocompatibility and stability in vivo, thereby improving imaging quality. Magnetic Hyperthermia (MHT): Fe3O4 nanoparticles can produce a thermal effect under the action of an external alternating magnetic field and can be used in magnetic hyperthermia therapy, especially in cancer treatment, to selectively kill cancer cells. Medication Delivery: Carboxylated dextran-modified ferric oxide nanoparticles can be used as drug carriers for drug delivery through their magnetism and the hydrophilicity of the carboxyl group. These nanoparticles can be combined with proteins or other biomolecules through covalent bonds to achieve targeted drug delivery. Biomolecular conjugation: The surface carboxyl functional groups of these nanoparticles can be coupled with biomolecules such as proteins, antibodies, and enzymes for biosensing and diagnosis.Nanoprobe construction: Carboxylated dextran-modified iron ferric oxide nanoparticles can be used to construct nanoprobes for biological detection and analysis.
