![MIT Researchers Create Jigs for Self-Assembling 3D Nanoscale Structures
[Researchers] began by creating an array of tiny posts on a substrate of silicon; they then coated the surface with materials called block copolymers, which have a natural tendency to assemble into long cylindrical structures.
By carefully controlling the initial spacing of the posts, Ross explains, the researchers were able to set the spacing, angles, bends and junctions of the cylinders that form on the surface. What’s more, she says, “Each of the two layers of cylinders can be independently controlled using these posts,” making it possible to create complex 3-D configurations.
