We investigated the electronic properties of highly ordered three-dimensional colloidal crystals of gold nanocrystals (7 ± 0.4 nm), called supracrystals. Two kinds of Au supracrystals with typical thicknesses of 300 nm and 5 μm, respectively, are probed for the first time with scanning tunneling microscopy/spectroscopy at 5 K revealing similar power law behavior and showing homogeneous conductance with the fingerprint of isolated nanocrystal. Potential applications evading the size-related risks of nanocrystals could be then considered.

it is very good
it is very good research , keep it continue ,
Dear Professor Robert Pope and Kondalarao tata, thank you for your comments, now I put another our publication about the electronic properties of supracrystals made of Au nanocrystals.
Re nanotechnology and gold particles discoveries. The effect of such research is greatly adding to the research of those seeking to eloborate upon the cultural electromagnetic theories of the 18th and 19th Century's, so called Romantic scientists such as Humboldt, Schelling, Kant and Oersted, etc.
quite interesting, it also helps further studies on electronic properties of nano gold particles
