Tuning Dipolar and Multipolar Resonances of Chiral Silicon Nanostructures for Control of Near field Superchirality
Dominic J. P. Koyroytsaltis-McQuire, Rahul Kumar, Tamas Javorfi +3
Chiral materials display a property called optical activity, which is the capability to interact differentially with left and right circularly polarised light. This leads to the ab…
Attomole enantiomeric discrimination of small molecules using an achiral SERS reporter and chiral plasmonics
Shailendra K Chaubeya, Rahul Kumar, Paula Laborda +6
Biologically important molecules span a size range from very large biomacromolecules, such as proteins to small metabolite molecules. Consequently, spectroscopic techniques which c…
Symmetry control of strong chiral light matter interactions in photonic nanocavities for efficient circularly polarised emission
Rahul Kumar, Ben Trodden, Anastasiia Klimash +6
Chiral excited electronic states of molecules have an intrinsic sense of handedness, or twist, and are the active component in energy efficient display technologies and in new phot…
Chiral Metafilms and Surface Enhanced Raman Scattering For Enantiomeric Discrimination of Helicoid Nanoparticles
Martin Kartau, Anastasia Skvortsova, Victor Tabouillot +10
Chiral nanophotonic platforms provide a means of creating near fields with both enhanced asymmetric properties and intensities. They can be exploited for optical measurements that…
Coupling of Plasmonic Hot Spots with Shurikens for Superchiral SERS-based Enantiomer Recognition
Olga Guselnikova, Roman Elashnikov, Vaclav Svorcik +6
Detection of enantiomers is a challenging problem in drug development as well as environmental and food quality monitoring where traditional optical detection methods suffer from l…
Near-field Probing of Optical Superchirality for Enhanced Bio-detection
Victor Tabouillot, Rahul Kumar, Paula L. Lalaguna +8
Nanophotonic platforms in theory uniquely enable < femtomoles of chiral biological and pharmaceutical molecules to be detected, through the highly localised changes in the chiral a…
Detecting Antibody-Antigen Interactions with Chiral Plasmons: Factors Influencing Chiral Plasmonic Sensing
D. Koyroytsaltis-McQuire, C. Gilroy, L. Barron +3
Chiral near fields possessing enhanced asymmetry (superchirality), created by the interaction of light with (chiral) nanostructures, potentially provide a route to novel sensing an…
