in this feature article, the methods of obtaining various mesostructures made of nanocrystals are described.With silver and silver sulfide, the nanocrystals are able to self organize in 2d and 3d super lattices to form supra crystals.With cobalt and ferrites nanocrystals, it has been possible to make ribbons, dots, or labyrinths.These mesostructures present new physical properties.
