A novel wet organic phase method to synthesize magnetite and nickel ferrite nanoparticles using stable ferric and nickel salts with stearic and cholic acids as encapsulation agents in anaerobic conditions has been reported. Adequate control over size and shape of particles was achieved by controlling reaction conditions including capping agent’s concentration. The shape, morphology, and average nanoparticle size were characterized by transmission electron microscopy (TEM). Particle diameters were further investigated using dynamic light scattering (DLS) studies. Particle structure and crystallite size were investigated using X-ray Powder Diffraction (XRD). The interaction of the carboxylate groups on the surface of the particles was studied using FTIR and Raman spectroscopy. The capped magnetic nanoparticles show promise for utilization as magnetic extractants and in colorimetric detection of DNA.
