We can orchestrate colloidal self-assembly through the careful design of an individual building block\u0026#39;s geometry and interactions. Typically, the blocks assemble piece-by-piece, like a jigsaw puzzle that assembles itself. This tactic, however, necessitates new orthogonal interactions with every additional building block. We take a different approach: folding a string of colloidal particles into desired geometries, echoing how polypeptides fold into proteins. By imposing a hierarchy of interactions, we find that we can select structures with near-perfect yield even with the most basic interaction sequences. This work presents an entirely new way to assemble colloidal structures and could be used to self-assemble mechanical or optical metamaterials such as a structure with a negative index of refraction.\u003Cbr \/\u003E\r\n\u003Cbr \/\u003E\r\n\u003Cstrong\u003EBio\u003C\/strong\u003E:\u0026nbsp;Angus McMullen completed his PhD at Brown University in 2015, where he studied the physics of translocation through solid-state nanopores---nanoscale biosensors with applications in DNA sequencing.
