Application of nanoparticles in chiral analysis and chiral separation
Chirality, 2021AbstractChiral molecules in relation to particular biological roles are stereoselective. Enantiomers differ significantly in their biochemical responses in biological environment. Despite the current advancement in drug discovery and pharmaceutical biotechnology, the chiral separation of some racemic mixtures continues to be one of the greatest ...

Chiral Separations in Capillary Electrophoresis
Chemical Reviews, 1999The marked increase in the number of communications on the utilization of electrophoresis for practical chiral separations within the last three years is the most evident, and the most important fact. It reveals that the basic period of intensive research in the field is finished. The search for chiral selectors discriminating racemates in a reasonably

2011
The most abundantly used route toward enantiopure chemical and biological products is through chiral separation of racemates. Several methods are available, of which crystallization is most used in industry, and chromatography is the most common analytical technique.

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 ...

Annual Review of Analytical Chemistry, 2010
The main goal of this review is to provide a brief overview of chiral separations to researchers who are versed in the area of analytical separations but unfamiliar with chiral separations. To researchers who are not familiar with this area, there is currently a bewildering array of commercially available chiral columns, chiral derivatizing reagents ...

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 ...

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 ...

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 ...

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.

Chiral On-Chip Separations of Neurotransmitters
Analytical Chemistry, 2003The fast on-chip determination of a range of compounds of relevance in the study and treatment of neurological disorders is demonstrated. These include dopamine and its metabolites methoxytyramine, homovanillic acid, noradrenaline, adrenaline, normetanephrine, and metanephrine, its artificial precursors DOPA and tyrosine; and the related compounds DOPS
