Nanotechnologists at the University of Twente's MESA+ research institute have developed a method whereby minuscule polystyrene spheres, automatically and under controlled conditions, form an almost perfect ball that looks suspiciously like a football, but about a thousand times smaller. The spheres organize themselves in such a way that they approach the densest arrangement possible, known as 'closest packing of spheres'. The method provides nanotechnologists with a new way of creating minuscule 3D structures.
