Hollow Fe₃O₄ nanoparticles

Product Name Hollow Fe₃O₄ nanoparticles Product Overview Hollow Fe3O4 nanoparticles are magnetic nano functional materials with cavities inside, with the chemical formula of Fe3O4. Its most prominent feature is its unique hollow structure, which effectively reduces material density and can buffer volume changes, enhancing structural stability. As a magnetic material, it has excellent magnetic response performance, Technical Parameter 颜色 Color 棕黑色粉末(可被磁铁吸引) Brown black powder (Can be attracted by a magnet) 粒径 Grain size ~150 nm 饱和磁化强度 Saturationmagnetizationintensity >60emu/g Product Features 1. Hollow structure: This structure not only reduces the weight of the material, but also increases its porosity, which helps to improve the adsorption capacity of substances and the efficiency of drug delivery systems. 2. Magnetic properties: Iron oxide nanoparticles have superparamagnetism and can rapidly magnetize and demagnetize under external magnetic fields without hysteresis. They are suitable for magnetic resonance imaging (MRI), magnetic hyperthermia (MHT), and drug delivery. 3. Biocompatibility and Biodegradability: Fe3O4 typically has good biocompatibility and biodegradability, making it suitable for use in the biomedical field. Application Fields 1.Tumor diagnosis and treatment: Iron oxide nanoparticles, due to their inherent properties, can achieve magnetic resonance imaging (MRI), magnetic hyperthermia (MHT), and drug delivery. 2.Drug delivery: Hollow iron oxide nanoparticles can be used as drug carriers to achieve targeted drug release through an external magnetic field, reducing drug dosage and side effects, and improving therapeutic efficacy. 3.Magnetic hyperthermia: In an alternating magnetic field, Fe3O4 nanoparticles can generate heat for the treatment of cancer, known as magnetic hyperthermia. By adjusting the size, adding components, changing shape, and surface modification of Fe3O4 nanoparticles, the specific heat absorption rate (SAR) can be improved, thereby enhancing the effectiveness of magnetocaloric therapy. 4.Environmental governance: Fe3O4 nanoparticles exhibit excellent adsorption performance, chemical stability, and easy separation and recovery in the field of wastewater treatment. 5.Biosensors: Due to their good biocompatibility and enzyme like activity, hollow iron oxide nanoparticles can be used for the construction of biosensors, improving detection sensitivity and specificity.
