Theory of Chiral Plasmonic Nanostructures Comprising Metal Nanocrystals and Chiral Molecular Media

ChemPhysChem, 2012
AbstractPlasmonic nanocrystals strongly interact with chiral molecular shells through electric and magnetic fields and in this way acquire new chiro‐optical properties. Transfer of chirality from biomolecules to the plasmonic resonances is a collective phenomenon and strongly depends on the geometry of nanostructure.

Gap plasmons inducing strong plasmonic chirality in planar metallic nanostructures

Journal of Physics D: Applied Physics, 2020
Abstract In this paper, an observation of chiral gap plasmons that induce strong optical chirality, spectroscopic circular dichroism (CD), and near-field enhancement in a planar metallic nanostructure is reported. The resulting chiral nanostructure consists of artificial gold nanoscale elements which are periodically fabricated on a ...

Circular dichroism from single plasmonic nanostructures with extrinsic chirality

Nanoscale, 2014
Circular dichroism (CD) studies on single nanostructures can yield novel insights into chiroptical physics that are not available from traditional ensemble-based measurements, yet they are challenging because of their weak signals. By introducing an oblique excitation beam, we demonstrate the observation and spectroscopic analysis of a prominent ...

Chiral plasmonic nanostructures: experimental and numerical tools

SPIE Proceedings, 2013
A combination of electron- and ion-beam lithographies has been applied to fabricate patterns of plasmonic nanoparticles having tailored optical functions: they create hot-spots at predefined locations on the nanoparticle at specific wavelengths and polarizations of the incident light field. Direct inscribing of complex chiral patterns into uniform nano-

Chiral Plasmonic Nanostructures via Colloidal Templating

2021
Nanophotonic and chiral plasmonics are among nanotechnology’s most intriguing and interdisciplinary fields and on the leap towards commercialisation. Chiral molecules are abundant in nature, our body and can even be found in the universe. The molecular handedness plays a significant role for their functions in many biological systems.

Plasmonic-enhancement of vibrational circular dichroism in plasmonic nanostructures embedding chiral drugs

Advanced Photonics Congress (IPR, Networks, NOMA, SOLITH, SPPCom)
We investigate the mid-infrared chiroptical response of Aluminum-doped Zinc Oxide (AZO)-based plasmonic nanostructures incorporating pharmaceutical chiral drug solutions. We systematically examine plasmon-enhanced vibrational circular dichroism (VCD) of the chiral drug solution to develop efficient chiroptical sensing techniques.
