Self-assembled three-dimensional chiral colloidal architecture
Abstract
A challenge for particle assembly is to bring different colloids together in a controlled and uniform way that goes beyond making lattice structures. Ben Zion et al. used DNA origami to pattern colloidal particles and assemble them into clusters with controlled chirality and composition. DNA belts wrapped flat along the curvature of a colloidal particle in an L-like shape. This meant that other achiral colloidal particles, each furnished with a specific complementary DNA belt, could only attach in one orientation.
