First and second chiplets are positioned along a surface to respectively cover first and second electrodes. The first electrode is activated to cause an attraction force between the first electrode and the first chiplet. The second electrode is deactivated allowing the second chiplet to rotate on the surface. While the first electrode is activated and the second electrode is deactivated, a rotation field is applied to cause the second chiplet to be oriented at a desired orientation angle, the first chiplet being prevented from rotating by the attraction force.

A method for forming a flow channel in a MIO structure includes positioning a plurality of sacrificial spheres along a base substrate, heating a region of the plurality of sacrificial spheres above a melting point of the plurality of sacrificial spheres, thereby fusing the plurality of sacrificial spheres together and forming a solid channel, electrodepositing material between the plurality of sacrificial spheres and around the solid channel, removing the plurality of sacrificial spheres to form the MIO structure, and removing the solid channel to form the flow channel extending through the MIO structure.

The spontaneous assembly of chiral structures from building blocks that lack chirality is fundamentally important for colloidal chemistry and has implications for the formation of advanced optical materials. Here, we find that purified achiral gold tetrahedron-shaped nanoparticles assemble into two-dimensional superlattices that exhibit planar chirality under a balance of repulsive electrostatic and attractive van der Waals and depletion forces. A model accounting for these interactions shows that the growth of planar structures is kinetically preferred over similar three-dimensional products, explaining their selective formation.

3D nanochannel interleaved devices for molecular manipulation are provided. In one aspect, a method of forming a device includes: forming a pattern on a substrate of alternating mandrels and spacers alongside the mandrels; selectively removing the mandrels from a front portion of the pattern forming gaps between the spacers; selectively removing the spacers from a back portion of the pattern forming gaps between the mandrels; filling i) the gaps between the spacers with a conductor to form first electrodes and ii) the gaps between the mandrels with the conductor to form second electrodes; and etching the mandrels and the spacers in a central portion of the pattern to form a channel (e.g., a nanochannel) between the first electrodes and the second electrodes, wherein the first electrodes and the second electrodes are offset from one another across the channel, i.e., interleaved. A device formed by the method is also provided.
