Chiral plasmonic nanostructures fabricated with circularly polarized light. [PDF]

Beilstein J Nanotechnol
Chiral plasmonic nanostructures (cPNSs) have garnered extensive interest across disciplines due to their strong interaction with circularly polarized light (CPL). Numerous fundamental studies have demonstrated the enhancement of chiroptic effects in molecular systems and quantum emitters facilitated by chiral metal nanostructures; for example, the ...

Biomacromolecular charge chirality detected using chiral plasmonic nanostructures [PDF]

Nanoscale Horizons, 2020
The charge distributions of solvent exposed surfaces of complex biomolecules such has proteins are unique fingerprints. The chirality of these charge distributions result in stereo-specific electrostatic interactions which help define how proteins interact with each other, contributing to specificity in protein – protein interactions.

Chiral plasmonic nanostructure of twistedly stacked nanogaps [PDF]

Chinese Optics Letters, 2021
Nanogap plasmonic structures with strong coupling between separated components have different responses to orthogonal-polarized light, giving rise to giant optical chirality. Here, we proposed a three-dimensional (3D) nanostructure that consists of two vertically and twistedly aligned nanogaps, showing the hybridized charge distribution within 3D ...

Tailoring Enhanced Optical Chirality: Design Principles for Chiral Plasmonic Nanostructures [PDF]

Physical Review X, 2012
Electromagnetic fields with strong optical chirality can be formed in the near-field of chiral plasmonic nanostructures. We calculate and visualize the degree of chirality to identify regions with relatively high values. This leads to design principles for a simple utilization of chiral fields.

Nanoimprinted Chiral Plasmonic Substrates with Three-Dimensional Nanostructures [PDF]

Nano Letters, 2018
We report a large-area fabrication method to prepare chiral substrates patterned with arrays of multilayer, three-dimensional nanostructures using a combination of nanoimprint lithography and glancing angle deposition. Several structures are successfully fabricated using this method, including L-shaped, twisted arc and trilayer twisted Au nanorod ...

Chiral Plasmonic Nanostructures Enabled by Bottom-Up Approaches [PDF]

Annual Review of Physical Chemistry, 2019
We present a comprehensive review of recent developments in the field of chiral plasmonics. Significant advances have been made recently in understanding the working principles of chiral plasmonic structures. With advances in micro- and nanofabrication techniques, a variety of chiral plasmonic nanostructures have been experimentally realized; these ...

Circular Dichroism in Low-Cost Plasmonics: 2D Arrays of Nanoholes in Silver

Applied Sciences, 2020
Arrays of nanoholes in metal are important plasmonic devices, proposed for applications spanning from biosensing to communications. In this work, we show that in such arrays the symmetry can be broken by means of the elliptical shape of the nanoholes ...

Chiral plasmonic DNA nanostructures with switchable circular dichroism [PDF]

Nature Communications, 2013
Circular dichroism spectra of naturally occurring molecules and also of synthetic chiral arrangements of plasmonic particles often exhibit characteristic bisignate shapes. Such spectra consist of peaks next to dips (or vice versa) and result from the superposition of signals originating from many individual chiral objects oriented randomly in solution.

Vibrational circular dichroism of plasmonic nanostructures embedding chiral drugs. [PDF]

Sci Rep
We investigate the mid-infrared chiroptical response of plasmonic nanostructures based on Al-doped ZnO and layers of an aqueous solution of Ladarixin, a chiral pharmaceutical currently under clinical trial for the treatment of type 1 diabetes. We explore the possibilities offered by localised surface plasmon resonances (LSPRs) for the enhancement of ...

Probing Specificity of Protein–Protein Interactions with Chiral Plasmonic Nanostructures [PDF]

The Journal of Physical Chemistry Letters, 2019
Protein-protein interactions (PPIs) play a pivotal role in many biological processes. Discriminating functionally important well-defined protein-protein complexes formed by specific interactions from random aggregates produced by nonspecific interactions is therefore a critical capability. While there are many techniques which enable rapid screening of
