An artist's representation of the structures produced by this self-assembly method shows a top-down view, with the posts produced by electron-beam lithography shown in blue, and the resulting self-assembled shapes shown in white.

A scanning electron microscope image shows a pattern produced by the MIT team's self-assembling polymer system. A grid of posts, seen as light-colored circles, controls the size and spacing of structures on the surface. Cylinders outside the grid form quite different shapes than those inside it, which are controlled by the posts.
