PARAGUAY-DELGADO, Francisco. Electron microscopy techniques used in the study of nanoparticles. Mundo nano [online]. 2020, vol.13, n.25, pp.101-131. Epub 25-Nov-2020. ISSN 2448-5691. https://doi.org/10.22201/ceiich.24485691e.2020.25.69626.
The phenomena involved in the interaction between electrons and matter are suitable signals for the study of nanoparticles. Each type of interaction is explained to know in detail the characteristics of nanomaterials such as: shape, size, crystallinity and composition. This work briefly describes the architecture and specific characteristics of three transmission electron microscopes, with the aim of demonstrating how the physical properties of nanomaterials can be studied and determined using techniques related to these instruments. A systematic and detailed study of two types of nanoparticles is also presented, specifically interpreting each experimental results obtained with different capacities of each electron microscopes used. The methodologies exposed in the materials characterization are reinforced with the inclusion of diverse nanomaterials studies.
