Abstract:
Although stereochemistry has been a central focus of the molecular sciences since Pasteur,
its province has previously been restricted to the nanometric scale. We have programmed the
self-assembly of micron-sized colloidal clusters with structural information stemming from a
nanometric arrangement. This was done by combining DNA nanotechnology with colloidal
science. Using the functional flexibility of DNA origami in conjunction with the structural rigidity
of colloidal particles, we demonstrate the parallel self-assembly of three-dimensional
microconstructs, evincing highly specific geometry that includes control over position, dihedral
angles, and cluster chirality
