We use Monte Carlo simulations and free-energy techniques to show that binary solutions of penta- and hexavalent two-dimensional patchy particles can form thermodynamically stable quasicrystals even at very narrow patch widths, provided their patch interactions are chosen in an appropriate way. Such patchy particles can be thought of as a coarse-grained representation of DNA multi-arm 'star' motifs, which can be chosen to bond with one another very specifically by tuning the DNA sequences of…

Rational Design and Self-Assembly of Two-Dimensional, Dodecagonal DNA Quasicrystals.
A rational strategy to assemble two-dimensional (2D), dodecagonal quasicrystals from branched DNA nanomotifs by balancing the rigidity and flexibility of the motifs, controlled by the introduction of interbranch "bridges".
Programming patchy particles to form three-dimensional dodecagonal quasicrystals.
This work investigates whether it can be design patchy particles that form three-dimensional quasicrystals, in particular targeting a quAsicrystal with dodecagonal symmetry that is made up of stacks of two- dimensional quasICrystalline layers.
Two-dimensional mixture of amphiphilic dimers and spheres: Self-assembly behaviour.
This work investigates by Monte Carlo simulation the equilibrium structure of a two-dimensional mixture of asymmetric dimers and spheres (disks), which observes a rich inventory of mesoscale structures at low temperature, such as clusters, lamellæ (i.e., polymer-like chains), and gel-like networks.
Self-Assembly Mechanisms of Triblock Janus Particles.
In agreement with experiment, it is found that nucleation of the Kagome lattice from solution follows a two-step mechanism, and the scaling behavior of the calculated barrier heights confirms a first-order liquid-Kagome phase transition.
Assembly of trivalent particles under confinement: from an exotic solid phase to a liquid phase at low temperature.
Using computer simulations, the phase diagram of a two-dimensional system of disk particles with three patches distributed symmetrically along the particle equator is studied and the effect of patch size within the single bond per patch regime is investigated.
Programming patchy particles to form complex periodic structures.
We introduce a scheme to design patchy particles so that a given target crystal is the global free-energy minimum at sufficiently low temperature. A key feature is a torsional component to the
Direct observation and rational design of nucleation behavior in addressable self-assembly
The experiments show that modifying the critical nucleus required to initiate structure growth can broaden the range of conditions over which self-assembly occurs and, consequently, can dramatically improve the final yield of correctly formed structures.
Shape control of soft patchy nanoparticles under confinement.
This work considers a composite, star-shaped particle made of f diblock copolymer chains uniformly grafted on a spherical colloid and investigates its first self-assembly stage both in the bulk and under lateral confinement, finding that the number of patches can be determined by tuning the degree of confinement imposed on the particle.
Formation and Fluctuation of Two-dimensional Dodecagonal Quasicrystal
The self-assembly of two-dimensional dodecagonal quasicrystal (DDQC) from patchy particles are investigated by Brownian dynamics simulations. The patchy particle has a five-fold rotational symmetry
How to design an icosahedral quasicrystal through directional bonding.
This work introduces a class of IQCs built from model patchy colloids that could be realized experimentally using DNA origami particles, and provides a potential route towards functional quasicrystalline materials.


Self-assembly scenarios of patchy colloidal particles in two dimensions.
We have investigated the self-assembly scenario of patchy colloidal particles in a two-dimensional system. The energetically most favourable ordered particle arrangements have been identified via an
DNA brick self-assembly with an off-lattice potential.
It is shown that the off-lattice model for DNA bricks results in robust self-assembly into a variety of target structures, although the relaxation of the geometric constraints leads to a more error-prone self- assembly pathway.
Self-Assembly of Patchy Particles.
The results show how precise arrangements of patches combined with patch "recognition" or selectivity may be used to control the relative position of particles and the overall structure of particle assemblies.
Reversible self-assembly of patchy particles into monodisperse icosahedral clusters.
This work systematically study the design of simple patchy sphere models that reversibly self-assemble into monodisperse icosahedral clusters and finds that the optimal patch width is a compromise between structural specificity and kinetic accessibility.
Formation of dodecagonal quasicrystals in two-dimensional systems of patchy particles.
Interestingly, in regions of parameter space near to that where the hexagonal crystals become stable, quasicrystalline structures with dodecagonal symmetry form on cooling from high temperature.
Direct Simulation of the Self-Assembly of a Small DNA Origami.
By using oxDNA, a coarse-grained nucleotide-level model of DNA, we are able to directly simulate the self-assembly of a small 384-base-pair origami from single-stranded scaffold and staple strands in
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.

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.
Controlled self-assembly of periodic and aperiodic cluster crystals.
These results confirm analytical predictions based on a mean-field approximation, providing insight into the stabilization of quasicrystals in soft macromolecular systems, and suggesting a practical approach for their controlled self-assembly in laboratory realizations using synthesized soft-matter particles.
Monodisperse self-assembly in a model with protein-like interactions.
This work thoroughly explores the thermodynamics and dynamics of self-assembly as a function of the parameters of the model and finds robust assembly of all target structures considered.
