Webbbond flexibility.17,18,34 Therefore, they assemble into flexible structures in a controlled fashion, but their shape is limited to spheres and they deform upon binding. Conversely, CSLBs consist of colloidal particles which provide a stable support for the lipid bilayer that is tunable in shape, size and material. WebbOur method is based on a controlled deformation of multiphase colloidal particles that can be selectively liquified, polymerized, dissolved and functionalized in bulk. We further …
Shaping colloids for self-assembly
Did you know?
WebbSelf-assembly is a key phenomenon whereby vast numbers of individual components passively interact and form organized structures, as can be seen, for example, in the morphogenesis of a virus. Generally speaking, the process can be viewed as a spatial placement of attractive and repulsive components. In this paper, we report on an … WebbShape complementarity is of paramount importance in molecular recognition, but has rarely been adopted in the self-assembly of colloidal particles, especially in the case of …
WebbProgress in colloid self-assembly crucially depends on finding preparation methods for anisotropic particles with recognition motifs to facilitate the formation of superstructures. Here, we demonstrate for the first time that direct 3D laser writing can be used to fabricate uniform populations of anisotropic cone-shaped particles that are suitable for self … Webbför 2 dagar sedan · A particular emphasis is given to solution-based syntheses that provide micron-sized colloids in high yields, and to assembly schemes that exploit the shape anisotropy of the building blocks ...
Webb19 apr. 2024 · Abstract A frame-guided wetting strategy is reported to synthesize highly uniform but asymmetrical colloidal particles from rings to oblate ellipsoids through symmetrical discs, which can self-assemble into diversified highly open 2D superstructures. Webb27 sep. 2011 · Reconfigurability of two-dimensional colloidal crystal structures assembled by anisometric particles capable of changing their shape were studied by molecular dynamics computer simulation. We show that when particles change shape on cue, the assembled structures reconfigure into different ordered structures, structures with …
WebbIn particular, the shape of building blocks has a fundamental role at the colloidal scale, as it can govern the self-organization of particles into hierarchical structures and ultimately into the desired material. Herein we report a simple and general approach to generate an entire zoo of new anisotropic colloids.
