“…According to Glotzer et al, [41] a patchy particle is a patterned particle with at least one well-defined patch through which the particle can experience a strongly anisotropic, highly directional interaction with other particles or surfaces. Note, this definition encompasses certain natural, biological macromolecules, for example, globular proteins.…”

“…Note, this definition encompasses certain natural, biological macromolecules, for example, globular proteins. For the sake of this review, we will limit our discussion to patchy particles with a spherical polymeric base and surface functionality, as shown in Figure 1, [41] or with spherical symmetry, as shown for the polymeric colloidal clusters depicted in Figure 2.

“…More recently, interest in this type of particle interactions has been renewed owing to the development of experimental methods that allow specific functionalization of colloids (see previous section). The 2004 article by Zhang and Glotzer [41] on the self-assembly of patchy particle introduced the term ''patchy particle'' and a simple model of empirical pair potentials between patch and core particle atoms to gain a general understanding of self-assembly. Many other models have been developed to describe patchy particle interactions and the main approaches are reviewed in the following section.…”

“…Several computational studies on the self-assembly of patchy particles have been reported and these have pushed the imagination of the patchy particle community to new heights. [36][37][38][39][40][41][42] However, the large-scale fabrication of patchy particles is still elusive and requires further research. [16,18,19] This article attempts to present the state-of-the-art in patchy particle fabrication technology and computational efforts for their description, together with a discussion of their potential applications.…”

The site‐specific engineering of colloidal surfaces has provided a powerful approach to pushing the boundaries of today's materials research. The resulting surface‐anisotropic and patchy particles have become the center of vital research areas, ranging from the need for large‐scale fabrication techniques to exploring new applications of these materials. This Review summarizes patchy particle fabrication techniques, including but not limited to particle and nanosphere lithography and glancing‐angle deposition. The variety of existing patchy particle fabrication techniques is revealed and the need for a scalable approach to high‐volume patchy particle production is identified. Ongoing modeling efforts describing patchy particle interactions and properties are reviewed as potential predictive tools. Research endeavors that deal with the directed assembly of patchy particles in electric and magnetic fields, as well as with supraparticular assembly through chemical interactions, are discussed. The Review is concluded with a note on the future application of patchy particles as phoretic motors.magnified image

“…One approach is to decorate the surface of colloidal particles with "sticky patches," made, for example, of synthetic organic or biological molecules and assigned to specific locations [15][16][17][18][19] . Bonding between particles occurs through patch-patch interactions, so that in principle the location and functionality of the patches can endow particles with bonding directionality and valence.…”

The ability to design and assemble 3-dimensional structures from colloidal particles is limited by the absence of specific directional bonds. As a result, complex or low-coordination structures, common in atomic and molecular systems, are rare in the colloidal domain. Here we demonstrate a general method for creating the colloidal analogues of atoms with valence: colloidal particles with chemically functionalized patches that can form highly directional bonds.These "colloidal atoms" possess all the common symmetries-and some uncommon ones-characteristic of hybridized atomic orbitals, including sp, sp 2 , sp 3 , sp 3 d, sp 3 d 2 , and sp 3 d 3 . Functionalizing the patches with DNA with single-stranded sticky ends makes the interactions between patches on different particles programmable, specific, and reversible, thus facilitating the self-assembly of particles into "colloidal molecules," including "molecules" with triangular, tetrahedral, and other bonding symmetries. Because colloidal dynamics are slow, the kinetics of molecule formation can be followed directly by optical microscopy. These new colloidal atoms should enable the assembly of a rich variety of new micro-structured materials. 2 IntroductionThe past decade has seen an explosion in the kinds of colloidal particles that can be synthesized 1,2 , with many new shapes, such as cubes 3 , clusters of spheres 4-6 and dimpled particles 7,8 reported. Because the self-assembly of these particles is largely controlled by their geometry, only a few relatively simple crystals have been made: face-centered and body-centered cubic crystals and variants 9 . Colloidal alloys increase the diversity of structures [10][11][12] , but many structures remain difficult or impossible to make. For example, the diamond lattice, predicted more than 20 years ago to have a full 3-dimensional photonic band gap 13 , still cannot be made by colloidal self-assembly because it requires 4-fold coordination. Without directional bonds, such low-coordination states are unstable.

Janus particles are characterized by different properties, such as color, charge, and functional groups at different sides. Owing to their complex behavior, Janus particles became a highly attractive research topic. Particularly, interesting groups of Janus particles are the ones that are sensitive to external signals such as change of temperature, pH, and light. These Janus particles are able to dynamically assemble/disassemble to forming very complex structures or reversibly/irreversibly change their shape by folding/bending. Recent progress in this fascinating field is discussed.
