Synthesis, Properties and Applications of Magnetic Iron Oxide Nanoparticles

Abstract

Superparamagnetic iron oxide nanoparticles are proving to be a class of novel probes useful for in vitro and in vivo cellular and molecular imaging. Iron oxide nanoparticles present unique properties that can be applied in targeted delivery of therapeutic agents, development of immunochromatographic tests, hyperthermia, conversion of a pro-drug to its active form. in general magnetic iron oxide powders are mainly produced by co-precipitation. Nanocomposite thin film present interesting magnetic, mechanical, electronic and optical properties due to their size-dependent phenomena. The sol-gel process is as efficient in preparing magnetic nanoparticles dispersed in different matrices and to produce thin films with accurate control over their morphology and purity
