Using a DNA scaffold to place molecules with Bohr's radius resolution

(Phys.org)—A new study demonstrates that researchers can control the distance between two molecules such that they can adjust the step size to as small as Bohr's radius. This proof-of-concept study using DNA origami techniques shows how molecular positioning can be fine-tuned at the atomic level at room temperature in solution. This work has applications for molecular architecture as well as templated chemical reactions. This study appears in Nature Nanotechnology.
