Chiral nanophotonic materials are promising candidates for biosensing applications
because they focus light into nanometer dimensions, increasing their sensitivity to the …

From small molecules to entire organisms, evolution has refined biological structures at the
nanoscale, microscale and macroscale to be chiral—that is, mirror dissymmetric. Chirality …

Nanoscopic chiroptics studies the spin-dependent asymmetric light–matter interactions at
the nanoscale, where the asymmetry can stem from the intrinsic properties of materials …

Circular dichroism (CD) spectroscopy has been widely demonstrated for detecting chiral
molecules. However, the determination of chiral mixtures with various concentrations and …

Quantitative analysis of chiral molecules in various solvents is essential. However, there are
still many challenges to enhancing the sensitivity in precisely determining both …

The chiral discrimination of enantiomers is crucial for drug screening and agricultural
production. Surface‐enhanced Raman scattering (SERS) is proposed for discriminating …

Although numerous natural materials exhibit chiral optical phenomena, they are typically
very weak. Chiral nanophotonic structures can significantly enhance the chiroptical …

The propagation of viruses has become a global threat as proven through the coronavirus
disease (COVID-19) pandemic. Therefore, the quick detection of viral diseases and …

In this work we undertake a systematic study of the optical chirality density of Laguerre-
Gaussian and Bessel laser beams tightly focused into nanoscale volumes. In particular we …

Infrared absorption spectroscopy is an effective tool for the detection and identification of
molecules. However, its application is limited by the low infrared absorption cross-section of …
