Modified Cyclodextrins for Chiral Separation offers a review of the latest advances in developing modified cyclodextrins as chiral selectors for various chromatographic and electromigration techniques. Over the years, many descriptions of chiral separation have appeared in academic journals and books, but most of them have been devoted to either the development of analytical methods and protocols or the summary of different chiral selectors, including cyclodextrins for chiral separation applications. This is in marked contrast to this volume which focuses on the research endeavors concerning the development of cyclodextrin derivatives specifically as either chiral mobile phases for capillary electrophoresis, or chiral stationary phases for various chromatographic techniques including gas chromatography, or high-performance liquid chromatography and supercritical fluid chromatography. The ongoing thread in this book is the synthesis of structurally-defined cyclodextrin derivatives and their applications in enantiomer separation by means of different analytical techniques. Modified Cyclodextrins for Chiral Separation is intended for those who are interested in expanding their knowledge of cyclodextrin chemistry and chiral separation, and in what cyclodextrin modification can be made to suit the needs of chiral selectors for different analytical techniques. It primarily focuses on the state-of-the-art cyclodextrin chemistry which is the basis for all chiral selectors used in these chiral separation techniques.

This book gives a comprehensive overview on the principles of physical and mathematical modelling of enantiomer separation by CE. Method development strategies are shown and cyclodextrins as a popular group of chiral selectors as well as some other selectors used as buffer additives for enantiomer separation in free solution are described.
Through modification, the natural cyclodextrins are effective templates for the generation of a wide range of molecular hosts. This makes it possible to tailor a cyclodextrin host to a particular guest, to meet specific requirements in the host-guest complex, and opens the way to diverse new areas of supramolecular chemistry. Metallocyclodextrins, rotaxanes and catenanes, as well as surface monolayers of modified cyclodextrins, are readily obtained. The native cyclodextrins serve as scaffolds on which functional groups and other substituents can be assembled, with controlled geometry. This results in substantially improved molecular recognition and procedures for chemical separation, including enantiomer discrimination, through guest binding. Access to the gamut of functional groups greatly expands the utility of cyclodextrins in chemical synthesis and provides catalysts which mimic the entire range of enzymic activity. Modifications to the cyclodextrins also lead to a wide range of photochemistry of cyclodextrin complexes, through which the enhancement of guest reactivity occurs; in addition, light harvesting molecular devices and photochemical frequency switches may be constructed. In solution, modified cyclodextrins have been used to construct molecular reactors, as well as molecular, temperature and pH sensors. At surfaces, they form semipermeable membranes and sensor electrodes. Such exciting fields of chemistry, made possible only through modifications to the natural cyclodextrins, are the subject of this book.
Prominent experts from around the world detail the chromatographic and electroseparation techniques they have developed for chiral separations on an analytical scale. Described in step-by-step detail to ensure successful experimental results, the procedures are presented as either general methods or as specific applications to substance classes and special compounds, with emphasis on high performance liquid chromatography and capillary electrophoresis techniques, but also including thin layer chromotographic, gas chromatographic, supercritical fluid chromatographic as well as recent electrochromotographic techniques.

Das weltweite Interesse an der Trennung von Enantiomeren, Spiegelbildern ein und derselben chemischen Verbindung, nimmt zu, da diese Formen beispielsweise verschiedene physiologische Wirkungen hervorrufen können. Eine hochaktuelle Technik der Stofftrennung in diesem Zusammenhang ist die Kapillarelektrophorese, die hier von den theoretischen Grundlagen bis hin zu analytischen Details und Anbieterlisten ausführlich beschrieben wird.

The series Topics in Current Chemistry presents critical reviews of the present and future trends in modern chemical research. The scope of coverage is all areas of chemical science including the interfaces with related disciplines such as biology, medicine and materials science. The goal of each thematic volume is to give the non-specialist reader, whether in academia or industry, a comprehensive insight into an area where new research is emerging which is of interest to a larger scientific audience. Each review within the volume critically surveys one aspect of that topic and places it within the context of the volume as a whole. The most significant developments of the last 5 to 10 years are presented using selected examples to illustrate the principles discussed. The coverage is not intended to be an exhaustive summary of the field or include large quantities of data, but should rather be conceptual, concentrating on the methodological thinking that will allow the non-specialist reader to understand the information presented. Contributions also offer an outlook on potential future developments in the field.
Though polychlorinated biphenyls (PCBs) have been banned in the United States for more than thirty years, the toxic effects of their presence in local environments continue to be a significant public health concern. PCBs: Human and Environmental Disposition and Toxicology brings together more than fifty established specialists on PCB toxicity to discuss recent trends and specialized investigations of PCB influences on the environment and on humans. Renowned scientists including Paul S. Cooke, Takeshi Nakano, Tomas Trnovec, Deborah C. Rice, Linda S. Birnbaum, and Charles S. Wong present cutting-edge research on Hudson River PCBs, human contamination, homologue profiles, high PCB exposure in Slovakia, and PCB effects on the thyroid hormone, nutrition, and estrogen levels in humans and animals. Focusing on the detection, movement, metabolism, toxicity, remediation, and risk assessment of PCB contamination, this multi-disciplinary study is a valuable resource for regulatory agencies and scientists working with PCBs.
