Physical Characterization of Nanomaterials in Dispersion by Transmission Electron Microscopy in a Regulatory Framework

Last updated on 20-1-2021 by Jill Alexandre



TEM is one of the few techniques that can identify nanoparticles according to the current definitions. This chapter focuses on the different steps required to analyze dispersed nanomaterials by TEM. Methodologies to obtain homogeneous and stable dispersions of colloidal nanomaterials and powders are presented. The preparation of TEM specimens to obtain a representative distribution of particles on the grid is discussed. The application of TEM imaging methods, electron diffraction and analytical TEM to obtain complementary information on the size, morphology, crystallographic structure, elec…
