|Maleimide (MAL) modified Fe304（50nm）
|The method of synthesizing single crystal magnetic microspheres by solvothermal method. Under high temperature and high pressure, this method can convert iron salt into iron hydroxide and ferrous hydroxide, and then reduce them to Fe3O4 nanoparticles. Specifically, FeCl3 · 6H2O is used as the iron salt, ethylene glycol is used as the solvent and reductant, and the reaction takes 8-72h at 200 ℃. The size of Fe3O4 nanoparticles increases from 200nm to 800nm.
|It is used in medical research, drug release, nanotechnology and new material research Fe3O4 is an inorganic substance with the chemical formula Fe3O4. It is a black crystal with magnetism, so it is also called magnetic iron oxide.
|Rod-shaped Fe3O4 （100nm）
|The rod like Fe3O4 material has recognizable magnetic moment direction, strong magnetism, good magnetic response, simple process, low cost, and is suitable for large-scale industrial production.
|Fitc Magnetic Silica Microspheres（100nm ）
|It has the advantages of uniform particle size distribution, good water dispersion, ultra-high specific surface area, narrow pore size distribution and large pore volume, and good biocompatibility. It is refrigerated at 4 ℃ and stored in a closed and clean manner.
|Fe3O4 is an inorganic substance with the chemical formula Fe3O4. It is a black crystal with magnetism, so it is also called magnetic iron oxide. It is regarded as a compound composed of ferrous oxide and ferric oxide (FeO · Fe2O3). This substance is insoluble in water, alkali solution, ethanol and other organic solvents. The natural ferric oxide is insoluble in acid solution, and it is easy to oxidize into ferric oxide (Fe2O3) in the air under humid conditions.
|Fe3O4 magnetic nanoparticles have been widely used in targeted drug carriers, cell separation, nuclear magnetic resonance, immunoassay, nucleic acid hybridization and other biomedical fields due to their dual advantages of both magnetic particles and nanoparticles.
|Titanium dioxide coated Fe3O4 hollow microsphere composite material is a nano core shell structure. Its core is a nano Fe3O4 hollow microsphere, and its shell is a titanium dioxide coating
|β- Hydroxybutyric acid (GHBA)-Fe3O4（20-50nm）
|β- Hydroxybutyric acid (GHBA) is an important component of ketone bodies in blood waves. BHBA is used by the brain as a source of energy, especially under the conditions of assisted lactation neonates and infants. It is inferred that as a further signal substance, it regulates energy center and acts as biological oxidation base to co regulate food intake.
|Citrate-stabilized Fe3O4 nanoparticles Fe3O4 Size:20nm
|(citrate-stabilized) Fe3O4 aqueous colloidal magnetic nanoparticles (CA-MNP) of size 8–10 nm using soft chemical route.The surface functionalization of Fe3O4 nanoparticles with citric acid was evident from infrared spectroscopy, thermal and elemental analyses, and zeta-potential measurements.
