Iron oxide nanoparticles were prepared and functionalized by succinamide based dendrimer. The resultant particles were characterized by XRD, VSM, and FTIR spectroscopy. The results indicate that the dendrimers has effectively functionalized the magnetite nanoparticles which remain dispersive and exhibited super-paramagnetism with a magnetization value of 33.2 emu/g in a field of 2T. Mean particle size as calculated from the AFM was found to be ~ 23 nm. Bovine serum albumin was immobilized on the magnetic nanoparticles as was confirmed by the FTIR results.
