DNA Programmable Self-Assembly of Planar, Thin-Layered Chiral Nanoparticle Superstructures with Complex Two-Dimensional Patterns

Yan Liu et al.

Summary: Planar, thin-layered chiral nanoparticle superstructures with complex 2D patterns were achieved through DNA programmable 2D supramolecular self-assembly, showing giant anisotropy of chiroptical responses in the dried state on substrates. This work opens up possibilities for constructing 2D chiral materials and manipulating chiral light-matter interactions on-chip via programmable self-assembly of nanoparticles.

Light-Responsive Dynamic DNA-Origami-Based Plasmonic Assemblies

Joonas Ryssy et al.

Summary: The article describes a method for remotely manipulating non-photoresponsive chiral plasmonic molecules (CPMs) using light, inducing DNA triplex link formation through a photoacid medium, resulting in spatial reconfiguration of CPMs. The overall chirality change depends on the fraction of CPMs undergoing reconfiguration, which is related to the intensity of incident light.

Chiral Systems Made from DNA

David Winogradoff et al.

Summary: The chemical structure of DNA has implications for self-organization and building functional nanostructures, with recent advances focusing on natural and synthetic chiral systems using DNA. The role of nucleic acid chirality in various situations, liquid crystal phases, and efforts to build chiral structures through DNA self-assembly are discussed. Current and proposed man-made nanostructures designed to probe or utilize DNA's chirality are also explored, from plasmonics to biosensing.

Long- and short-ranged chiral interactions in DNA-assembled plasmonic chains

Kevin Martens et al.

Summary: The study confirms complex chiral optical fields in complex metal structures. The experiment demonstrates that by using DNA origami, placing an achiral nanosphere between a pair of distant gold nanorods arranged in a chiral fashion can achieve chiral transfer and observe enhanced circular dichroism signals.

Reconfigurable Chirality of DNA-Bridged Nanorod Dimers

Brian Hyun-jong Lee et al.

Summary: Gold nanorod dimers bridged by double-stranded DNA exhibit variable chiral configurations depending on the chemical and ionic properties of the solvent medium. The chiral behavior is governed by the twist-stretch coupling of the DNA and intermolecular interactions between nanorods. Changes in depletant or ion concentration of the solvent medium can lead to different classes of configurational responses by the dimers, including chirality-switching behavior.

Prescribing Silver Chirality with DNA Origami

Yinan Zhang et al.

Summary: In this research, a new method was developed to fabricate silver nanostructures with three-dimensional chirality using DNA origami-enabled aqueous solution metallization strategy. The study found that the chirality of silver nanostructures can be controlled through synergetic interactions, resulting in the synthesis of helical silver patterns with well-defined chirality and pitches. This method opens up new pathways for synthesizing programmable inorganic materials with arbitrary morphology and chirality.

Chiral Photomelting of DNA-Nanocrystal Assemblies Utilizing Plasmonic Photoheating

Oscar Avalos-Ovando et al.

Summary: The study demonstrates that chiral light can control chiral plasmonic photomelting by using a chiral DNA-assembled nanorod pair as a model system. The nonlinear chiroptical response of the plasmonic system is attributed to the chiral photothermal effect resulting in selective melting of DNA linker strands. The proposed mechanism can be used to develop chiral photoresponsive systems controllable with circularly polarized light.

Assembling gold nanobipyramids into chiral plasmonic nanostructures with DNA origami

Jinyi Dong et al.

Summary: In this study, gold nanobipyramids (AuNBPs) were assembled into static and dynamic chiral plasmonic nanostructures using DNA origami. Compared to conventional chiral dimers of gold nanorods (AuNRs), AuNBP dimers exhibited more intriguing chiroptical responses, suggesting they could be a superior alternative for constructing chiral plasmonic nanostructures for biosensing.
