Self-Assembly in 3D Using Magnetic Levitation: Using Magnetic Levitation for Three Dimensional Self-Assembly (Adv. Mater. 36/2011)
The image shows three plastic components (cut from a polymethylmethacrylate sheet using a laser cutter to form the letters G, M, and W) levitating in an aqueous solution of MnCl2 between two NdFeB magnets. The letters have a preprogrammed distribution of densi-ties, which is achieved by applying tapes with different densities to their surfaces. As reported by George M. Whitesides and co-workers on page 4134, the balance of magnetic and gravitational forces acting on the letters controls their vertical position and orientation.
