Fig 3 The programming self-assembly of nanoparticles induced by DNA molecular templates (a) Illustration of the rolling process. (b) TEM images of the rectangular DNA origami dressed with two chains of AuNPs. (c) TEM images of the tubular DNA origami dressed with AuNPs, which form 3D AuNP helices. (d) Left: Schematic model (inset) and corresponding TEM images of the self-assembled LH gold nanorods (AuNRs) and gold nanoparticles (AuNPs) nanostructures. Right: Schematic model (inset) and corresponding TEM images of the self-assembled RH AuNR and AuNP nanostructures. Scale bars in the insets are 25 nm. (e) The measured CD spectra of the LH and RH helical superstructures and the corresponding bifacial structures. (a–c) Reprinted with permission from Ref. 140.
