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