Abstract

A rapid and simple method for the evaluation of the average size of the hard core - shell nanoparticles in a sample is presented. It is based on the combination of two procedures (calcination and modelling) easy to perform. The application to a series of magnetite – amino acid nanoparticles (amino acid: aspartic, glutamic, proline, tryptophan, arginine) leads to satisfactory values for the average size of the nanoparticles if they are compared with those experimentally determined by Transmission Electron Microscopy..
