Enhancement of Optical Chirality Using Metasurfaces for Enantiomer-Selective Molecular Sensing
Applied Sciences, 2021 Circular dichroism (CD) is a physical property observed in chiral molecules by inducing the difference of absorption between left- and right-handed circularly polarized light (CPL). Circular dichroism spectroscopy is widely used in the field of chemistry

Circular Dichroism of DNA [PDF]
European Journal of Biochemistry, 1970 The circular dichroism of sixteen DNA samples from fourteen species has been determined. Plots of molar ellipticity against base composition show considerable scatter, which is much too great to be accounted for in terms of reproducibility of materials and measurements.

Estimation of flattening coefficient for absorption and circular dichroism using simulation [PDF]
, 2009 The absorbance and circular dichroism (CD) of suspensions is lower than if the same amount of chromophore were uniformly distributed throughout the medium. Several mathematical treatments of this absorption flattening phenomenon have been presented using

Micro-volume couette flow sample orientation for absorbance and fluorescence linear dichroism [PDF]
, 2004 Linear dichroism (LD) can be used to study the alignment of absorbing chromophores within long molecules. In particular, Couette flow LD has been used to good effect in probing ligand binding to DNA and to fibrous proteins.

Measuring circular phase-dichroism of chiral metasurface
Nanophotonics, 2019 The ability of chiral media to differentiate circularly polarized light is conventionally characterized by circular dichroism (CD) which is based on the difference in the absorption of the incident light for different polarizations.

Breaking the 200nm limit for routine flow linear dichroism measurements using UV synchrotron radiation [PDF]
, 2008 The first synchrotron radiation flow linear dichroism spectra are reported. High-quality spectral data can be collected from 450 nm down to 180 nm in contrast to the practical cutoff of not, vert, similar200 nm on benchtop instruments.
