The ability to design and synthesize ever more complicated colloidal particles opens the possibility of self-assembling a zoo of complex structures, including those with one or more self-limited length scales. An undesirable feature of systems with self-limited length scales is that thermal fluctuations can lead to the assembly of nearby, off-target states. We investigate strategies for limiting off-target assembly by using multiple types of subunits. Using simulations and energetics… 

Self-Assembly of DNA-Grafted Colloids: A Review of Challenges

DNA-mediated self-assembly of colloids has emerged as a powerful tool to assemble the materials of prescribed structure and properties. The uniqueness of the approach lies in the sequence-specific,

Self-assembly of chiral tubules.

This work adds chirality to the model monomer and a lock-and-key interaction and obtains good control of the self-assembled tubule pitch to explain some fundamental features of microtubules.

Thermodynamic Size Control in Curvature-Frustrated Tubules: Self-Limitation with Open Boundaries.

We use computational modeling to investigate the assembly thermodynamics of a particle-based model for geometrically frustrated assembly, in which the local packing geometry of subunits is

Simulation is used to show that a strategy of minimal positive design allows the self-assembly of networks equivalent to the 8 semiregular Archimedean tilings of the plane, structures not previously realized in simulation.

Directed self-assembly of a colloidal kagome lattice

This paper shows how colloidal spheres can be induced to self-assemble into a complex predetermined colloidal crystal—in this case a colloidal kagome lattice—through decoration of their surfaces with a simple pattern of hydrophobic domains, and encodes the target supracolloidal architecture.

Multifarious assembly mixtures: Systems allowing retrieval of diverse stored structures

This work addresses a fundamental limitation of the existing approaches to self-assembly, and proposes a scheme to create “multifarious assembly mixtures,” which self-assemble many different large structures from a set of shared components.

Equilibrium mechanisms of self-limiting assembly.

This review focuses on the more specialized class of self-limiting assembly, which describes equilibrium assembly processes resulting in finite-size structures, and describes the physical mechanisms that select equilibrium assembly size, as well as potential limitations of finite- size selection.

Patterns without Patches: Hierarchical Self-Assembly of Complex Structures from Simple Building Blocks

Using computer simulations, it is shown that structures of the same genre can be obtained from a solution of simple isotropic spheres, with control only over their sizes and a small number of binding affinities.

Self-assembly of "Mickey Mouse" shaped colloids into tube-like structures: experiments and simulations.

The self-assembly of anisotropic patchy particles with a triangular shape was studied by experiments and computer simulations and it was found that the internal structure of the tubular fragments could either be straight or twisted into so-called Bernal spirals.

Irregular model DNA particles self-assemble into a regular structure.

It is shown that a model particle, whose rotational properties lie between those of the vertices of the 6.6.6 and 4.8.8 networks, can self-assemble into a network built from three types of vertex, thereby allowing the formation of more than one type of binding motif.

Shaping colloids for self-assembly.

This paper reports a simple and general approach to generate an entire zoo of new anisotropic colloids based on a controlled deformation of multiphase colloidal particles that can be selectively liquified, polymerized, dissolved and functionalized in bulk.
