DNA Origami‐Guided Assembly of the Roundest 60–100 nm Gold Nanospheres into Plasmonic Metamolecules

DNA origami can provide programmed information to guide the self‐assembly of gold nanospheres (Au NSs) into higher‐order supracolloids. Molecularly precise and truly 2D/3D integration of Au NSs is possible using DNA origami‐enabled assembly, and the resulting assemblies have potential applications in plasmonics and metamaterials. However, the relatively small size (<60 nm) and randomly faceted Au NSs that have been used thus far in DNA...
