Magnetic nanoparticles are multifunctional having therapeutic applications in developing cancer treatment by nano-imaging for early detection of the disease and as a carrier for drug delivery. Studies in magnetic particles for such purposes bring about stimuli responsive release capability’s with increased dosage control reducing toxicity. In this report, we describe the synthesis and characterization of magnetic Fe and Fe-Co nanoparticles encapsulated in polypyrrole. These systems were chosen for their properties as biodegradable metals in hopes of vivo delivery of cancer curing drugs. Also, we are interested in testing and comparing the chemical and magnetic properties of monometallic Fe and bimetallic Fe-Co (with different metal ratios) systems. Preliminary data showed the formation of magnetic nanoparticles with sizes starting from 1.9 nm, according to Transmission Electron Microscopy (TEM) analyses.
