As nanostructures are being tailored and synthesised whose functionality depends on increasing complexity at ever finer length scales the challenges to the science of characterization are increasing. The convergence between the complexity and length scales of organic macromolecules and nanostructures has lead, logically, to the adaptation of techniques previously the preserve of the biosciences to the physical arena. One recent example of such an adaptation is electron tomography, where a 3D image of an object is reconstructed from a series of electron micrographs, to the study of inorganic nanostructures. However, the demands of materials science, and the capability of its microscopy community, create both new problems and opportunities for the application of the technique. Results from recent research to circumvent these problems and explore the opportunities will be presented. These results will include approaches increasing the volume and density of specimens which can be successfully studied and the application of the technique to unravelling real nanostructural problems such as the nature of metallic contacts to nanotubes and morphologies of quantum confinement objects.
