About 25 micrometers wide and 100 micrometers tall these "flowers," created by scientists at Harvard, are made from barium carbonate and silica. Through a complex chemical process, the researchers can induce these tiny flower-like structures to self-assemble. By controlling the environmental temperature different shapes and sizes can be coaxed to spontaneously form.
This method of manufacturing nano-scale structures has implications for the nano-industry in the long run. But for now, I would really love to order a custom made nano-bouquet for my girlfriend, accompanied by a false color image, as the bouquet would be next to invisible to the naked eye.
