Ferrofluid currently has a variety of applications but is not as selective when it comes to imaging. This is interest for applications like MRI or bioimaging. Addition of a photosensitive compound could induce a magnetic affect while under excitation by electromagnetic radiation. This research aims to synthesis and characterize FeCo nanoparticles with a photochromic dye attached. The goal is to have a fluorescent nanoparticle that is both stable and photomagnetic. In this research, photomagnetic means a particle that can change magnetic properties in the presence of electromagnetic radiation.<br/>To test the hypothesis that stable photomagnetic particles could be synthesized, a decomposition reaction of ironpentacarbonyl and dicobaltoctacarbonyl was performed to form FeCo nanoparticles then a dye loading step was performed to create the completed FeCo-dye complex. This was then characterized using fluorescence and UV-vis spectrometer along with an estimate of magnetization. The results show that there is a fluorescent nanoparticle being produced from the experiment that does retain some magnetic properties. More characterization still needs to be performed.<br/>In conclusion there is potential for these FeCo nanoparticles to exhibit fluorescence when bound to a photochromic dye. While this does look promising there still needs to be more work done to characterize the nanoparticles and their properties.
