“…in a liquid environment and that these methods have the potential to be easily scalable. The next two techniques, glancing-angle vapor deposition (Figure 5d) [8,71] and nanoparticle lithography (Figure 5e), [18,19] involve vapor deposition onto close-packed planar particle assemblies. The last technique involves the use of liquid streams in capillaries for fabrication of bi-, tri-and multi-phasic particles from the Lahann, [13,15] Kumacheva [64] and Whitesides [67] groups (Figure 5f).…”

“…Also, the geometry of the pattern depends on the relative position of the layer to which the modified particle belonged. In a subsequent work, Zhang et al [18] used reactive ion etching on the top-most layer and found that they were able to create particles with sp, sp 2 , and sp 3 patch geometries.…”

“…A wide variety of anisotropic particles with diverse anisotropy in size, shape [1][2][3][4][5][6][7] and chemical functionality [8][9][10][11][12][13][14][15][16][17][18][19][20] has been explored. Within such a large diversity of anisotropic particles, significant attention has been given lately to the study of surface-anisotropic particles, that is, particles exhibiting multiple surface functionalities, while often having an isotropic polymer core.…”

“…[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. We start with the introduction of the concept of patchy particles, using the anisotropy dimensions suggested by Glotzer and Solomon.…”

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

“…1 for examples). Over the last decade or so, researchers have synthesized particles with anisotropic shapes such as ellipsoids [29], cubes [30], dimples [31], rods [32], clusters of spheres [33] and many more [34][35][36][37][38][39]. Enormous strides have also been made in controlling inter-particle interactions.…”

The glass transition is the most enduring grand-challenge problem in contemporary condensed matter physics. Here, we review the contribution of colloid experiments to our understanding of this problem. First, we briefly outline the success of colloidal systems in yielding microscopic insights into a wide range of condensed matter phenomena. In the context of the glass transition, we demonstrate their utility in revealing the nature of spatial and temporal dynamical heterogeneity.We then discuss the evidence from colloid experiments in favor of various theories of glass formation that has accumulated over the last two decades. In the next section, we expound on the recent paradigm shift in colloid experiments from an exploratory approach to a critical one aimed at distinguishing between predictions of competing frameworks. We demonstrate how this critical approach is aided by the discovery of novel dynamical crossovers within the range accessible to colloid experiments. We also highlight the impact of alternate routes to glass formation such as random pinning, trajectory space phase transitions and replica coupling on current and future research on the glass transition. We conclude our review by listing some key open challenges in glass physics such as the comparison of growing static lengthscales and the preparation of ultrastable glasses, that can be addressed using colloid experiments.
