Assembly line : Hydrophobic, repulsive double‐layer, and van der Waals interactions have been employed in the sequential self‐assembly of microfabricated silicon parts in aqueous solution. Control of the assembly sequence is realized by simply changing the pH of the solution. The fabrication of column‐ and barrel‐shaped microstructures and closed‐link microchain structures is demonstrated through a two‐step self‐assembly process (see picture).
