Triblock colloids for directed self-assembly.
Methods for functionalizing micrometer-sized colloidal spheres with three or more zones of chemical functionality (ABA or ABC) are described. To produce ABA triblock colloids, we functionalized the north pole, south pole, and equator to produce what we call X, Y, and K functionality according to the number of allowed nearest neighbors and their spatial arrangements. These synthesis methods allo...
متن کاملSelf-assembly of colloids with liquid protrusions.
A facile and flexible synthesis for colloidal molecules with well-controlled shape and tunable patchiness is presented. Cross-linked polystyrene spheres with a liquid protrusion were found to assemble into colloidal molecules by coalescence of the liquid protrusions. Similarly, cross-linked poly(methyl methacrylate) particles carrying a wetting layer assembled into colloidal molecules by coales...
متن کاملSelf-Assembly: From Nanoscale to Microscale Colloids
Self-assembly is a fundamental mechanism by which structures form in materials. Over the past decades, a primary focus has been to relate materials’ behaviors to the spatial arrangement of their fundamental building blocks. These building blocks may comprise atoms, molecules, macromolecules and colloidal particles. It is well known that the same chemical substance can have vastly different prop...
متن کاملSelf-assembly of Colloids for Plastic Capillary Electrochromatography Chip
In this work we have developed and characterized a novel fabrication process for producing dense, porous array of silica particles packed inside a plastic microfluidic channel. The novel approach relies on in-situ crystallization of colloidal silica particles within specific regions of a microchannel defined by plasma processing. These selfassembled silica colloids through a plastic microchanne...
متن کاملInfluence of fluctuating membranes on self-assembly of patchy colloids.
A coarse-grained computational model is used to investigate the effect of a fluid membrane on patchy-particle assembly into biologically relevant structures motivated by viral cores and clathrin. For cores, we demonstrate a nonmonotonic dependence of the promotion of assembly on membrane stiffness. If the membrane is significantly deformable, cores are enveloped in buds, although this effect is...
