Electron Tomography is a powerful imaging technique used in materials science and biology to visualize the three-dimensional structure of samples at the nanoscale. It involves taking multiple two-dimensional images of a specimen from different angles using an electron microscope. These images are then computationally reconstructed to create a detailed 3D representation. This method is particularly useful for studying complex structures, such as cell organelles or nanomaterials, where traditional imaging techniques may fall short. By providing insights into the arrangement and interactions of components, Electron Tomography enhances our understanding of various scientific fields, including biochemistry and nanotechnology.
