Abstract :

In this article, preparation of magnetic nanostructured iron oxide particles (IOs) and their surface functionalization with oleic acid, 3-Aminopropyltrimethoxysilane (APMTS) and Ag nanoparticles are reported. IOs particles were prepared by co-precipitation method and colloidal silver nanoparticles were synthesized by polyol method. The nanoscale IOs particles (<100nm) exhibited paramagnetic property and surface functionalization did not alter its magnetism. Colloidal stability of IOs particles is dependent on the nature of the surfactants. Necked IOs, and IOs functionalized with APTMS and Ag nanoparticles are polydisperse in size while IOs functionalized with oleic acid are monodisperse. Such functionalized IO nanoparticles can be employed in medical diagnostics, environmental remediation and energy harvesting technology.
