β-Cyclodextrin-Self-Assembled Nanochannel Membrane for the Separation of Chiral Drugs
ACS Applied Nano Materials, 2020 The fabrication of a membrane with the capability of chiral selective transport is a big challenge in the membrane separation of chiral drugs. To solve the problem of chiral selectivity in membrane separation, drug/metabolite transport (DMT) in the cell ...

Transfer of Chirality for Memory and Separation
2010Transfer of chirality is an intriguing issue worth studying to understand better the origin of life and for possible technological applications. In the last few years we have been working in this area studying the chain of events that begins with induction, reaches a permanent transfer (chiral memory) and extends in some cases to a (quasi-)reversible ...

The development of biphasic chiral recognition in chiral separation
Chirality, 2018AbstractIn chiral separation, enantioseparation factor is an important parameter which influences the resolution of enantiomers. In this current overview, a biphasic chiral recognition method is introduced to the readers. This method can significantly improve the enantioseparation factor in two‐phase solvent through adding lipophilic and hydrophilic ...

Subsecond chiral separations on a microchip
ELECTROPHORESIS, 2004AbstractFast chiral separation of DNS‐amino acids could be realized using microchip electrophoresis with fluorescence detection. For this purpose, highly sulfated cyclodextrins (HS‐γ‐CD) were used as chiral selectors enabling high selectivity. Even subsecond separation of DNS‐tryptophan, DNS‐norleucine, DNS‐phenylalanine, DNS‐methionine, and DNS ...

Microchip electrophoresis for chiral separations
ELECTROPHORESIS, 2003AbstractMicrochip electrophoresis (MCE) is a promising new technique for the separation of enantiomers. This recently introduced technique enables chiral separations to be performed in seconds on tiny micromachined devices. This review is intended to give a brief introduction into the principles of chiral separations with MCE with regard to methodology

A Reversible Gel for Chiral Separations
Analytical Chemistry, 2004The use of a guanosine gel as a chiral selector in capillary electrophoresis is introduced. Guanosine gels are reversible organized media that are formed through the self-association of guanosine compounds. Their degree of organization and their physicochemical properties can be modulated through variations in guanosine monomer concentration, pH ...

Chiral separation of agricultural fungicides
Journal of Chromatography A, 2011Fungicides are very important and diverse environmental and agricultural concern species. Their determination in commercial formulations or environmental matrices, requires highly efficient, selective and sensitive methods. A significant number of these chemicals are chiral with the activity residing usually in one of the enantiomers.
