Product Name
Name:OA Coated Fe3O4 Nanoparticles
Product Overview
The co precipitation method is used to prepare oleic acid modified iron oxide nanoparticles, which is a method of co precipitating two or more metal ions in solution to form nanoparticles. The obtained nanoparticles have oil solubility and can be dispersed in organic solvents such as n-hexane and chloroform. The key to co precipitation method lies in controlling the reaction conditions, including the ratio of reactants, pH value of the solution, reaction temperature, and stirring speed, in order to obtain the ideal nanoparticle size and magnetic properties. Through this method, oleic acid modified iron oxide nanoparticles with superparamagnetism, high biocompatibility, and good dispersibility can be prepared, providing an important material foundation for biomedical and nanotechnology fields.

Product Features
Superparamagnetism: These nanoparticles possess superparamagnetism and can rapidly magnetize and demagnetize under an external magnetic field, making them suitable for use in magnetic resonance imaging (MRI) and magnetic hyperthermia (MHT). Oil solubility: Oleic acid modification makes Fe3O4 nanoparticles oil soluble and can be dispersed in organic solvents such as cyclohexane, chloroform, tetrahydrofuran, etc. Surface modification: The modification of oleic acid not only enhances the stability of nanoparticles, but also provides functional surface functional groups, which facilitate further chemical modification or binding of biomolecules. Stability: The modification of oleic acid enhances the chemical and physical stability of Fe3O4 nanoparticles, helping to maintain their long-term storage and use.
Application Fields
Magnetic resonance imaging (MRI) contrast agent: Due to its superparamagnetism, oleic acid modified Fe3O4 nanoparticles can serve as negative contrast agents for MRI, enhancing image contrast and helping to observe tissues and organs more clearly. Biosensing and Detection: In biosensors, Fe3O4 nanoparticles can serve as signal converters or enhancers to improve the sensitivity and selectivity of detection. Doped water in oil nanoemulsion: Fe3O4 nanoparticles modified with oleic acid can be dispersed in the oil phase and used for doping water in oil nanoemulsion to enhance its functionality. Environmental governance: used for the adsorption and separation of pollutants, especially in water treatment and soil remediation. Energy storage: Fe3O4 nanoparticles have potential applications in supercapacitor and battery technology due to their excellent conductivity and cycling stability
