Abstract Scope |
Several strategies have been established for the synthesis of magnetic nanoparticles with tunable sizes, morphologies and magnetic properties. Most of these reports are based on synthesis of magnetic nanoparticles that involve use of environmentally malignant organic solvents and high temperature conditions. Here we present a facile, rapid, low temperature approach to synthesize crystalline Fe3O4 mesostructures with high magnetic properties via a microwave-assisted sonochemical method and studied the effects of conventional crystal growth modifiers: oleic acid (OA) in the evolution of Fe3O4 morphology. We observed that the TEM investigations for OA as crystal growth modifier resulted in primary nanocrystals of hexagonal prism like morphologies. The as-synthesized Fe3O4 exhibit superparamagnetic properties with high saturation magnetization and have no residual magnetism. Further, the cytotoxicity analysis of as-synthesized samples on H9c2 cells revealed that the samples were safe to cells at higher concentrations. |
