WebHere, we put forward a scheme that enables optical separation and simultaneous discrimination of single chiral particles using focused vector beams with OAM. Such focused vector vortex beams carrying radial-splitting optical chirality can selectively trap one enantiomer inside or outside the intensity maxima depending on the sign of the OAM ... WebIn CLC, such sites will exhibit enantiotopic discrimination, irrespective of their average (improper) symmetry. This enantiodiscrimination results mainly from the different ordering of the interchanging enantiomers. Various illustrative examples of flexible prochiral molecules which exhibit chiral discrimination in CLC are discussed in Chap. V.
