Directed Self-Assembly (image) University of Chicago Caption This atomic force microscope image shows directed self-assembly of a printed line of block copolymer on a template prepared by photolithography. The image was colored and scaled by the microscope's software. The density of patterns in the template (bounded by the thin lines) is two times that of the self-assembled structures (the ribbons).
