DNA in Supramolecular Chemistry and Nanotechnology


Book Description

This book covers the emerging topic of DNA nanotechnology and DNA supramolecular chemistry in its broader sense. By taking DNA out of its biological role, this biomolecule has become a very versatile building block in materials chemistry, supramolecular chemistry and bio-nanotechnology. Many novel structures have been realized in the past decade, which are now being used to create molecular machines, drug delivery systems, diagnosis platforms or potential electronic devices. The book combines many aspects of DNA nanotechnology, including formation of functional structures based on covalent and non-covalent systems, DNA origami, DNA based switches, DNA machines, and alternative structures and templates. This broad coverage is very appealing since it combines both the synthesis of modified DNA as well as designer concepts to successfully plan and make DNA nanostructures. Contributing authors have provided first a general introduction for the non-specialist reader, followed by a more in-depth analysis and presentation of their topic. In this way the book is attractive and useful for both the non-specialist who would like to have an overview of the topic, as well as the specialist reader who requires more information and inspiration to foster their own research.




Intramolecular Charge Transfer


Book Description

Bridging the gap between the multitude of advanced research articles and the knowledge newcomers to the field are looking for, this is a timely and comprehensive monograph covering the interdisciplinary topic of intramolecular charge transfer (ICT). The book not only covers the fundamentals and physico-chemical background of the ICT process, but also places a special emphasis on the latest experimental and theoretical studies that have been undertaken to understand this process and discusses key technological applications. After outlining the discovery of ICT molecules, the authors go on to discuss several important substance classes. They present the latest techniques for studying the underlying processes and show the interplay between charge transfer and the surrounding medium. Examples taken from nonlinear optics, viscosity and polarity sensors, and organic electronics testify to the vast range of applications. The result is a unique information source for experimentalists as well as theoreticians, from postgraduate students to researchers.







Electron Transfer in Chemistry and Biology


Book Description

Electron Transfer in Chemistry and Biology An Introduction to the Theory Alexander M. Kuznetsov Russian Academy of Sciences, Moscow, Russia Jens Ulstrup Technical University of Denmark, Lyngby, Denmark Electron transfer is perhaps the single most important physical event in chemical, electrochemical, photochemical, biochemical, and biophysical processes. The focus and ubiquity of electron transfer is intriguing and exciting but a coherent and comprehensive approach to this topic is at the same time a challenge. Electron Transfer in Chemistry and Biology provides a thorough and didactic approach to the theoretical basis of electron transfer phenomena. Not only does it offer a full introduction to this area and a discussion of its historical development, it also gives detailed explanations of difficult issues, for example, long-range electron transfers, stochastic and dynamic processes, and biological features. A wide variety of readers will find this volume of great interest, ranging from final year undergraduate students, postgraduate students and university lecturers, to research staff in numerous fields including medical companies, electronics industry, catalysis research and development, chemical industry and some hospitals.
