If we have a 4cm x 4cm x 4cm cube, the surface area is 4cm x 4cm times the number of sides, so = 16cm x 6. If we cut this cube into 8 smaller cubes, each with equal dimensions, what would be the sum of the total area of all new surfaces?

• Fake 1

• Fake 2

• 2cm x 2cm x 6 sides x 8 cubes = 192 cm^2. One of nanotechnology’s advantages rises from having more surface area when materials are reduced in size (not necessarily changing the volume), enhancing many material properties such as chemical reactivity and other surface effects.

A gold structure, when present in solution as a nanostructure, can exhibit different colours. Why is that?

• Gold nanoparticles absorb and scatter light at different colours, from red to blue to black, depending on their size. This is due to conduction electrons on the surface of each particle which oscillate in resonance with incident light. The colour results from the wavelength of this light being of comparable size to that of the particle. (phenomenon called “Localized Surface Plasmon Resonance”)

What are gold nanoparticles useful for?

• Fake 1

• Gold nanoparticles can be used in therapeutics such as target drug delivery to optimize the biodistribution of drugs to diseased organs. It can also be used in diagnostics in cancer research, to target tumors and provide detection. At INL, we use gold nanoparticles to improve the photocatalytic efficiency of nanoTiO2 by decorating it with gold nanostars for water treatment (organic compound degradation).
