Abstract
This work describes the self-assembly of millimeter-sized helical componentsfabricated by replica molding from sections of drill bits and boltsinto 3D aggregates via capillary forces. The components form aggregates of different geometry: components derived from drill bits formed regular helices, and those derived from bolts formed irregular warped sheets. Enantioselective interactions between components derived from drill bits resulted in the formation of aggregates with complex structures, including enantiomerically pure helices, aggregates with multiple helical segments, and chiral aggregates formed from achiral components, i.e., spheres.
