Capillary Electrophoretic Separation and Quantification of Tryptophan and Tyrosine Enantiomers in Nutritional Supplements Using Sulfated‐β‐Cyclodextrin

open access: yesJournal of Chemistry, Volume 2026, Issue 1, 2026.
Enantioselective analysis of two aromatic amino acids, namely, tryptophan (TRP) and tyrosine (TYR), was investigated by incorporating sulfated‐β‐cyclodextrin as the enantioselective agent. Performance of chiral separation was studied using background electrolyte (BGE) pH, applied voltage, capillary temperature, and the time of sample injection, which ...

Effects of Rigid Conjugated Groups: Toward Improving Enantioseparation Performances of Chiral Porous Organic Polymers

open access: yes, 2019
The construction of chiral porous materials for practical enantioseparation remains a great challenge. As chiral compounds might display a distinctive spatial orientation in diastereoisomeric complexes between enantiomers and selectors, we reasoned that ...

Experimental generation of optimally chiral azimuthally‐radially polarized beams

open access: yesNanophotonics, Volume 14, Issue 23, Page 4079-4090, 02 November 2025.
Abstract We implement a paraxial azimuthally‐radially polarized beam (ARPB), a novel class of structured light beams that can be optimal chiral (OC), leading to maximum chirality density at a given energy density. By using vectorial light shaping techniques, we successfully generated a paraxial ARPB with precise control over its features, validating ...
