WebThe optical activity of a metal nanocluster (NC) is induced either by an asymmetric arrangement of constituents or by a dissymmetric field of a chiral ligand layer. Herein, we unveil the origin of chirality in Ag29 NCs, which is attributed to the intrinsically chiral atomic arrangement. The X-ray crystal str WebCHIRALPAK AGP phase uses α 1 -acid glycoprotein (AGP) as the chiral selector immobilized on spherical 5 μm silica particles. Bonded AGP is a very stable protein that tolerates pure organic solvents, elevated temperatures and pH values from 4 to 7. Operated in reversed-phase mode, CHIRALPAK AGP column separates enantiomers of an …
