“…During in-situ synthesis (fig. 4b), precursors in solution (for example, metal ions, silicification precursors or lipid molecules) adsorb/react/deposit on DNA origami templates with or without prescribed nucleation sites [128][129][130][131][132] and generate continuous architectures shaped by the morphologies of the templates or their cavities 16,133 . This approach promotes nanoarchitectures with almost arbitrary, user-defined geometries in solution or on a surface 28,131,132,134 .…”

Biological materials are self-assembled with near-atomic precision in living cells, whereas synthetic 3D structures generally lack such precision and controllability. Recently, DNA nanotechnology, especially DNA origami technology, has been useful in the bottom-up fabrication of well-defined nanostructures ranging from tens of nanometres to sub-micrometres. In this Primer, we summarize the methodologies of DNA origami technology, including origami design, synthesis, functionalization and characterization. We highlight applications of origami structures in nanofabrication, nanophotonics and nanoelectronics, catalysis, computation, molecular machines, bioimaging, drug delivery and biophysics. We identify challenges for the field, including size limits, stability issues and the scale of production, and discuss their possible solutions. We further provide an outlook on next-generation DNA origami techniques that will allow in vivo synthesis and multiscale manufacturing.

“…The DNA-templated Cu structures had enhanced luminescence and florescence stability, although their electrical behavior was not studied. Jia et al [ 86 ] demonstrated localized binding of Cu 2+ and Ag + with protruding DNA sequences on 2D DNA origami via N–ion interactions. Subsequent metallization was performed through reduction-generated site-specific metal patterns with ~10 nm resolution.…”

Bottom-up fabrication using DNA is a promising approach for the creation of nanoarchitectures. Accordingly, nanomaterials with specific electronic, photonic, or other functions are precisely and programmably positioned on DNA nanostructures from a disordered collection of smaller parts. These self-assembled structures offer significant potential in many domains such as sensing, drug delivery, and electronic device manufacturing. This review describes recent progress in organizing nanoscale morphologies of metals, semiconductors, and carbon nanotubes using DNA templates. We describe common substrates, DNA templates, seeding, plating, nanomaterial placement, and methods for structural and electrical characterization. Finally, our outlook for DNA-enabled bottom-up nanofabrication of materials is presented.

“…DNA nanostructures were also used as molds to control the growth of finite-sized metal nanostructures [ 28 , 29 , 30 , 31 ]. Furthermore, finite structures created by selective metallization schemes [ 32 ] and DNA structure-assisted lithography [ 33 ] showed promising progress for nanoscale DNA-assisted metallization. The best way to confirm successful metallization is to measure nanowire resistance or conductance.…”

Self-assembly nanofabrication is increasingly appealing in complex nanostructures, as it requires fewer materials and has potential to reduce feature sizes. The use of DNA to control nanoscale and microscale features is promising but not fully developed. In this work, we study self-assembled DNA nanotubes to fabricate gold nanowires for use as interconnects in future nanoelectronic devices. We evaluate two approaches for seeding, gold and palladium, both using gold electroless plating to connect the seeds. These gold nanowires are characterized electrically utilizing electron beam induced deposition of tungsten and four-point probe techniques. Measured resistivity values for 15 successfully studied wires are between 9.3 × 10−6 and 1.2 × 10−3 Ωm. Our work yields new insights into reproducible formation and characterization of metal nanowires on DNA nanotubes, making them promising templates for future nanowires in complex electronic circuitry.
