Some Assembly Required

Abstract
Materials science has traditionally involved the study of the self-assembly of atoms or molecules into bulk thermodynamic phases. In her Perspective, [Glotzer][1] predicts that this field will be revolutionized by new materials made from larger, more complex building blocks designed to assemble in specific ways. These building blocks allow potentially much greater control over a material's properties, enabling the design rather than the selection of materials for specific uses.
