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 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.

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

Plasmonic Chiral Nanostructures: Chiroptical Effects and Applications [PDF]
Advanced Optical Materials, 2017 The plasmonic chiroptical effect has been used to manipulate chiral states of light, where the strong field enhancement and light localization in metallic nanostructures can amplify the chiroptical response. Moreover, in metamaterials, the chiroptical effect leads to circular dichroism (CD), circular birefringence (CB), and asymmetric transmission ...

Biomacromolecular Stereostructure Mediates Mode Hybridization in Chiral Plasmonic Nanostructures [PDF]
Nano Letters, 2016 The refractive index sensitivity of plasmonic fields has been exploited for over 20 years in analytical technologies. While this sensitivity can be used to achieve attomole detection levels, they are in essence binary measurements that sense the presence/absence of a predetermined analyte.

Gold-Nanoparticle-Based Chiral Plasmonic Nanostructures and Their Biomedical Applications
Biosensors, 2022 As chiral antennas, plasmonic nanoparticles (NPs) can enhance chiral responses of chiral materials by forming hybrid structures and improving their own chirality preference as well. Chirality-dependent properties of plasmonic NPs broaden application potentials of chiral nanostructures in the biomedical field.
