“…The interest of the structural aspects of biopolymers has risen over the past 10 years as properties such as selfassembly and self-organization has been demonstrated for many of the biological molecule and biopolymer systems [134]. Self-assembling collagen arrays, DNA origami, and now protein origami clearly demonstrate how elaborate and complex nanostructured surfaces can be generated de novo from a relatively simple collection of biopolymers and little or no scaffolding using a bottom up strategy [134][135][136][137][138][139]. The hope is that larger-scale self-assembly of even more elaborate nanopatterned surface will be possible using similar principles and approaches.…”

Helium ion microscopy (HIM) is a relatively new high-resolution nanotechnology imaging and nanofabrication tool. HIM offers a near-molecular resolution (approaching that of TEM) combined with a simplicity of sample preparation and high depth of field similar to SEM. Simultaneously, the technique is not limited by the surface roughness as scanning probe microscopy (SPM) techniques or by the surface charging or radiation damage like SEM. In our review, we consider general principles, advantages, and prospects of HIM application in polymer science. Examples of high-resolution imaging of polymer-based nanocomposites, polymer nanoparticles, nanofibers, nanoporous materials, polymer nanocrystals, biopolymers, and polymer-based photovoltaic and sensor devices are presented. We compare the HIM's applicability with other modern imaging techniques: SPM and SEM.

“…Much DNA assembly work has therefore focused on creating precise geometries to harness novel optical behaviour emerging from the coupling of NP surface plasmons in chiral assemblies [27][28][29] . However, while these properties have been demonstrated using bulk measurements such as circular dichroism or ultraviolet-visible spectrometry, there have been only a few studies carefully characterizing the plasmonic properties of single nanostructures 30 which reveals the crucially important uniformity in the assembly process. For future applications of DNA-based assemblies, characterization of the effect of DNA origami on the plasmonic properties of NP assemblies is thus essential.…”

DNA origami based assembly of gold nanoparticle dimers for surface-enhanced Raman scattering

Plasmonic sensors are extremely promising candidates for label-free single-molecule analysis but require exquisite control over the physical arrangement of metallic nanostructures. Here we employ self-assembly based on the DNA origami technique for accurate positioning of individual gold nanoparticles. Our innovative design leads to strong plasmonic coupling between two 40 nm gold nanoparticles reproducibly held with gaps of 3.3±1 nm. This is confirmed through far field scattering measurements on individual dimers which reveal a significant red shift in the plasmonic resonance peaks, consistent with the high dielectric environment due to the surrounding DNA. We use 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. This demonstrates that DNA origami is a powerful tool for the high-yield creation of SERS-active nanoparticle assemblies with reliable sub-5 nm gap sizes.

“…Furthermore, multiscaffold DNA origami ribbons have been shown to be powerful tools for the assembly of plasmonic waveguides consisting of linear AuNP arrays. 36 As previously mentioned, plasmonic coupling often produces enhanced local field strengths, and such enhancements are significantly dependent on the geometry. The ability to precisely the tailor NP arrangement through the DNA origami technique may lead to the strong near-field coupling of surface plasmons and inspire new sensing techniques.…”

Nanoparticles are among the most fascinating materials because of their unique size-dependent properties. The spatial positioning of the nanoparticles with a nanoscale precision will greatly enhance their potential for use in the fabrication of functional materials and devices. Recently, the development of DNA nanotechnology has enabled the construction of two-and three-dimensional, precisely addressable nanostructures and devices based on DNA sequence design and programmable assembly. Advances in conjugating DNA with nanoparticles can bridge these two technologies and provide scientists with a new tool to study material transportation and energy transfer at a nanometer scale. In this review, we summarize the recent progress in this emerging research field, which includes not only the static arrangements of inorganic nanoparticles but also the dynamic regulation of organic and biological units at a nanometer scale. With the rapid development in this field, new challenges and new possibilities will emerge and bring about fruitful achievements with a significant impact on future work.
