Limited to the size of DNA origami, which are approximate to 100 nm, it is hard to assemble more intricate plasmonic nanostructures in large scale. Herein, we used rectangular DNA origami as the template to anchor two 30-nm gold nanoparticles(Au NPs) which induced dimers nanostructures. ...

since the DNA origami template was prepared in a buffer containing Mg2+, which is always present in the metallization reaction system. The ion forms of selected metal elements Mg, Ag, Co, Ni, Pd, and Pt used for simulation were [Mg(H2O)4]2+, [Ag(H2O)2]+, Co(H2O)2Cl2, Ni(H2O)...

(c) By designing the "X" pattern of the arrangement of DNA capturing strands on both sides of a two-dimensional DNA origami template, AuNRs were assembled into AuNR superstructures with the origami intercalated between neighboring AuNRs[42] https://engine.scichina.com/doi/10.1360/N972018-00888...
We describe two general approaches to the utilization of DNA origami structures for the assembly of materials. In one approach, DNA origami is used as a prefabricated template for subsequent assembly of materials. In the other, materials are assembled simultaneously with the DNA origami, i.e. the...
(SPECTRA). An aptamer sequence specific to DU145 cells was selectively attached to the edges of a rectangular DNA origami template via biotin-neutravidin conjugation. Gold nanorods labeled with 4-mercaptobenzonitrile (4-MBN) were then arranged on the template in a nanoantenna configuration(a). In...
