Magnetite Nanoparticle Co-precipitation Synthesis, Characterization, and Applications: Mini Review

Magnetite nanoparticles (MNP) are nowadays considered a real wealth to the enormously developing world owing to the several characteristics they pose. In addition to the shared nanofeatures, superparamagnetism facilitates repetitive use for several rounds. Synthesis of MNPs was accomplished through plenty of methods using different iron precursors and reaction conditions with different surface modifications so as to obtain monodispersity and superparamagnetism in a diameter less than 30 nm. Among them, coprecipitation was found to be the easiest way for MNP synthesis. The synthesized MNPs have been used for different applications including biochemical as well as biomedical aspects. This mini review provides a brief report of synthesis of MNPs using coprecipitation approach along with the most employed characterization techniques. Moreover, safety and biomedical and biochemical applications were also covered.
