Virtual molds cast colloid Blue Mosque A way to direct colloids to self-assemble in an almost infinite variety of configurations has been devised. The technique relies on the creation of a pre-determined pattern of magnetic fields to generate a 'virtual mold' to dictate the final position of the particles. |
