  ABSTRACT: This work focuses on the synthesis and physicochemical properties of stabilized magnetite nanoparticles (SMNPs) using the eco-friendly agent starch as a stabilizer. Nanoparticles were prepared by the Fe2+/Fe3+ ions coprecipitation approach in alkali media (ammonia hydroxide) as a precipitating agent. Relevant properties of the obtained nanoparticles were investigated by a vibrating sample magnetometer (VSM) and dynamic light scattering (DLS). The morphology was monitored by transmission electron microscope (TEM) and scanning electron microscope (SEM). The average crystallite size of SMNPs, about 10 nm, is observed from TEM and DLS. The presence of starch in the synthesis medium lowers the magnetite particle size, increases the dispersion of the particles, and promotes the superparamagnetic nature of MNPs.
