Abstract

The applications of HAADF STEM and EFTEM tomography as an imaging and analytical tool for macromolecular structures and three-dimensional (3D) nanostructures are discussed. Electron tomography, as a means to reconstruct three-dimensional objects from a series of two-dimensional projections, is adapted from the life sciences to meet the demands of materials analysis at the nanometer length scale. STEM HAADF shows good resolution and sensitivity, especially to high atomic number particles in a low atomic number matrix. EFTEM imaging is used extensively in biological tomography, not for elemental imaging, but in zero-loss mode in which the spectrometer is used to filter the inelastic scattering.
