In this presentation we show a method for the preparation of magnetite nanoparticles with diameter and density controlled particle. Nanoparticles were synthesized in the chitosan matrix, two sets of samples were prepared. The density of the nanoparticles was increased by controlling the amount of reactants. Measurements of X-ray diffraction showed that the nanoparticles have a lattice parameter of 0.839 Ǻ and have an average diameter of 12.6 nm. Images of transmission electron microscopy showed monodisperse particles with very narrow log-normal size distribution. The obtained network parameter shows that nanoparticles are of high purity. Mossbauer spectroscopy measurements, performed at room temperature showed spectra due to magnetically blocked particles, and this effect mainly due to the magnetic interaction between the nanoparticles.
