In recent years, magnetic nanoparticles have become increasingly attractive to researchers for their wide scope of applications across numerous fields. For this reason, there is no shortage of literature available on magnetic nanoparticle synthesis and characterization. Iron Cobalt nanoparticles cannot be found in such an abundance due to their tendency to quickly oxidize when exposed to air, but these specific nanoparticles offer relatively high magnetization values so if they could be synthesized reliably they could have a great potential impact across many field. This project aims to synthesize these nanoparticles in such a way that they become the base for biocompatible ferrofluid for the specific application of magnetic drug targeting.<br/>Surfactants allow for air stabilization and biocompatibility to be achieved in the FeCo nanoparticles. In this project, oleic acid and oleylamine are used as surfactants to result in a carbon coating around the nanoparticles. Chloro(triphenylphosphine) gold is used following and in addition to the carbon surfactants to create a gold layer. The resulting particles there for should have air stabilization and biocompatibility achieved through the use of carbon and gold surfactants. These resulting particles are taken through size separation methods such as centrifuge and fractionation will be employed in order to achieve uniform size distributions at the desired particle diameter. UV-Vis spectroscopy, EDX imaging, and ICP-MS will be used to characterize the particles by confirming and quantifying surfactant ratios to iron and cobalt and magnetization values will determine the relation between particle diameter and magnetic field strength.
