Reversible self-assembly and directed assembly of DNA-linked micrometer-sized colloids.
We present a technique for the directed assembly and self-assembly of micrometer-scale structures based on the control of specific DNA linkages between colloidal particles. The use of DNA links combined with polymer brushes provides an effective way to regulate the range and magnitude of addressable forces between pairs (and further combinations) of different particles. We demonstrate that the ...
متن کاملTriblock 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 کاملTemplate-Directed Self-Assembly of 10-μm-Sized Hexagonal Plates
This article presents a strategy for the fabrication of ordered microstructures using concepts of design inspired by molecular self-assembly and template-directed synthesis. The self-assembling components are 4-μm-thick hexagonal metal plates having sides 10 μm in length (“hexagons”), and each template consists of a 4-μm-thick circular metal plate surrounding a central cavity, the perimeter of ...
متن کاملSpecific and reversible DNA-directed self-assembly of oil-in-water emulsion droplets.
Higher-order structures that originate from the specific and reversible DNA-directed self-assembly of microscopic building blocks hold great promise for future technologies. Here, we functionalized biotinylated soft colloid oil-in-water emulsion droplets with biotinylated single-stranded DNA oligonucleotides using streptavidin as an intermediary linker. We show the components of this modular li...
