Abstract

Water compatible magnetite nanoparticles have been successfully prepared by ultrasound-assisted reversed chemical precipitation method. This method enables synthesis of gram-scale magnetite nanoparticles in a rapid, low-cost, reproducible and easy-to-handle manner. More, this preparation method is easily scalable to meet industrial requirements. XRD, SEM, FTIR, N2-sorption and room-temperature VSM are the techniques used to investigate the structural, textural, morphological and magnetic properties of the obtained nanoparticles. The results show that the obtained nanoparticles display superparamagnetic behavior, hidrophillicity, homogeneous particle sizes of ~20 nm and low agglomeration tendency, making them very promising platform for biomedical applications. The factors governing the formation of magnetite nanoparticles by ultrasound-assisted reversed chemical precipitation are discussed extensively..
