Fig. 2. (a) High Resolution Transmission Electron Microscopy (TEM) image of gold nanoparticles attached to the virus. (b) Model showing a virus with site-specific attached gold nanoparticles. (c) Fourier filtered image of a gold nanoparticle, showing surface facets. Virus particles and arrangements of gold nanoparticles on the virus were accurately identified for the first time by high resolution TEM.

(Middle) Atomic force microscopy (AFM) image of a carbon nanotube with electrical contacts for practical electronic devices based on carbon nanotubes. (Right) High resolution TEM image of grapheme sheets (Inset: model showing atomic arrangement of carbon. Graphene is a new class of materials for future nanoelectronics.

Fig. 4. Cross-sectional HRTEM images of nanowires patterned along the (a) [1-10] and (b) [100] crystallographic directions. Both are ~10nm in width and height. For the first time, these nanowire structures were successfully fabricated with precise control of their dimension and crystallographic orientation by a combination of wafer bonding and lithography methods. In the same manner, future nanowires can be fabricated using different materials, such as Ge, GaAs and Ge on Si. This will allow for exploration of these materials properties when scaled down to the quantum regime.
