  • The dependence of the magnetic responsiveness on magnetite nanoparticle size has been studied. Monodisperse magnetite nanoparticles of 10 nm diameter were prepared by an ultrasonically enhanced co-precipitation procedure. A carboxyl-functionalised solvothermal approach was applied to synthesise magnetite nanoparticles with an average size of 30 nm. The particle sizes and their distribution have been determined by analysing TEM images and considering nanoparticle formation mechanisms. The magnetic characterisation revealed an inverse dependence between the magnetite nanoparticle size and its ability to respond to external magnetic fields, which was explained by the decrease of magnetic...

  • Ultrasound was throughout employed to enhance the co-precipitation process for the synthesis of magnetite nanoparticles (Fe3O4) and the St€ ober approach for the preparation of magnetite-silica nanocomposites (Fe3O4/SiO2). The synthesised magnetite nanoparticles exhibited single-domain nano-crystallites with a uniform spherical morphology, a narrow size distribution (ca. 10 nm), and negligible coercive field (~5 Oe). The prepared magnetite-silica nanocomposites possessed a mono core-shell structure with spherical morphology, biologically coherent size (ca. 100 nm), and discrete mono-domain behaviour. The crystalline structure-magnetic behaviour relationships of the nanomaterials were ...
