TL;DR: R rigid DNA origami scaffolds can be used to assemble metal nanoparticles, quantum dots and organic dyes into hierarchical nanoclusters that have a planet-satellite-type structure and can be positioned along the radial DNA spacers of the nanostructures.

TL;DR: This work uses surface-enhanced Raman scattering (SERS) to demonstrate local field enhancements of several orders of magnitude through detection of a small number of dye molecules as well as short single-stranded DNA oligonucleotides, demonstrating that DNA origami is a powerful tool for the high-yield creation of SERS-active nanoparticle assemblies with reliable sub-5 nm gap sizes.

TL;DR: L Luo and his coworkers have developed a new approach to construct DNA hydrogels, which are crosslinked networks swollen in an aqueous phase and lack precise structural control and specifi c responses.

TL;DR: By first aligning and then toggling the orientation of DNA-origami-scaffolded nanoparticle helices attached to a substrate, this work is able to reversibly switch the optical response between two distinct circular dichroism spectra corresponding to either perpendicular or parallel helix orientation with respect to the light beam.

TL;DR: A DNA-origami-based "tensegrity triangle" structure that assembles into a 3D rhombohedral crystalline lattice with an open structure in which 90% of the volume is empty space is presented.
