Bioelectrochemistry: Fundamentals, Experimental Techniques and Application, covers the fundamental aspects of the chemistry, physics and biology which underlie this subject area. It describes some of the different experimental techniques that can be used to study bioelectrochemical problems and it describes various applications of biolelectrochemisty including amperometric biosensors, immunoassays, electrochemistry of DNA, biofuel cells, whole cell biosensors, in vivo applications and bioelectrosynthesis. By bringing together these different aspects, this work provides a unique source of information in this area, approaching the subject from a cross-disciplinary viewpoint.
Bioelectrochemistry: Principles and Practice provides a comprehensive compilation of all the physicochemical aspects of the different biochemical and physiological processes. The role of electric and magnetic fields in biological systems forms the focus of this second volume in the Bioelectrochemistry series. The most prominent use of electric fields is found in some fish. These species generate fields of different strengths and patterns serving either as weapons, or for the purpose of location and communication. Electrical phenomena involved in signal transduction are discussed by means of two examples, namely excitation-contraction coupling in muscles and light transduction in photoreceptors. Also examined is the role of electrical potential differences in energy metabolism and its control. Temporal and spatial changes of the potential difference across the membranes of nerve cells are carefully evaluated, since they are the basis of the spreading and processing of information in the nervous system. The dielectric properties of cells and their responses to electric fields, such as electrophoresis and electrorotation, are dealt with in detail. Finally, the effects of magnetic fields on living systems and of low-frequency electromagnetic fields on cell metabolism are also considered. Further volumes will be added to the series, which is intended as a set of source books for graduate and postgraduate students as well as research workers at all levels in bioelectrochemistry.
Das führende Werk auf seinem Gebiet - jetzt durchgängig auf den neuesten Stand gebracht! Die theoretischen Grundlagen der Elektrochemie, erweitert um die aktuellsten Erkenntnisse in der Theorie des Elektronentransfers, werden hier ebenso besprochen wie alle wichtigen Anwendungen, darunter modernste Verfahren (Ultramikroelektroden, modifizierte Elektroden, LCEC, Impedanzspektrometrie, neue Varianten der Pulsvoltammetrie und andere). In erster Linie als Lehrbuch gedacht, läßt sich das Werk aber auch hervorragend zum Selbststudium und zur Auffrischung des Wissensstandes verwenden. Lediglich elementare Grundkenntnisse der physikalischen Chemie werden vorausgesetzt.
Volume I provides an in-depth discussion of the most recent developments of crucical biosensor components. It concentrates on the interface between the analyte phase and the detector, namely, the implementation of novel recognition elements, including nucleic acids, and of leading-edge technology in the construction of responsive thin layers. Thus, the reader can obtain a foretaste of achievable future progress in the field.
This book serves as a manual of research techniques for electrochemically active biofilm research. Using examples from real biofilm research to illustrate the techniques used for electrochemically active biofilms, this book is of most use to researchers and educators studying microbial fuel cell and bioelectrochemical systems. The book emphasizes the theoretical principles of bioelectrochemistry, experimental procedures and tools useful in quantifying electron transfer processes in biofilms, and mathematical modeling of electron transfer in biofilms. It is divided into three sections: Biofilms: Microbiology and microbioelectrochemistry - Focuses on the microbiologic aspect of electrochemically active biofilms and details the key points of biofilm preparation and electrochemical measurement Electrochemical techniques to study electron transfer processes - Focuses on electrochemical characterization and data interpretation, highlighting key factors in the experimental procedures that affect reproducibility Applications - Focuses on applications of electrochemically active biofilms and development of custom tools to study electrochemically active biofilms. Chapters detail how to build the reactors for applications and measure parameters
Bioenergetics, the topic of volume 5 of this Series, is concerned with the energetics, the kinetics, and the mechanisms of energy conversion in biological systems. This phenomenon can be investigated on diffe rent levels of complexity. On a global level the role of biological pro cesses for the steady state of our enviroment is considered. At the physiological level, the relation between energy input and the physiolo gical state of an organism is of interest, while at the cellular level the biochemical pathways for degradation and synthesis of all relevant substrates is investigated. At present the majority of bioenergetic stu dies pertain to the molecular level. The processes in a cell are cataly zed by a large number of proteins called enzymes. The enzymes in volved in energy transduction can be considered as molecular ma chines which transform energy from one form into another, or transfer energy from one process to another. Living systems operate far from equilibrium and are open in the ther modynamic sense, i. e. they exchange energy and matter with the sur roundings. Chapter 1 presents the principles of non equilibrium thermo dynamics applied to biological systems. About 0. 05% of the energy from the sunlight which reaches the surface of the earth is used by plants and algae as well as some bacteria to synthesize organic com pounds, and thus supplies all organisms with the energy necessary for life.
Key features include: Self-assessment questions and exercises Chapters start with essential principles, then go on to address more advanced topics More than 1300 references to direct the reader to key literature and further reading Highly illustrated with 450 figures, including chemical structures and reactions, functioning principles, constructive details and response characteristics Chemical sensors are self-contained analytical devices that provide real-time information on chemical composition. A chemical sensor integrates two distinct functions: recognition and transduction. Such devices are widely used for a variety of applications, including clinical analysis, environment monitoring and monitoring of industrial processes. This text provides an up-to-date survey of chemical sensor science and technology, with a good balance between classical aspects and contemporary trends. Topics covered include: Structure and properties of recognition materials and reagents, including synthetic, biological and biomimetic materials, microorganisms and whole-cells Physicochemical basis of various transduction methods (electrical, thermal, electrochemical, optical, mechanical and acoustic wave-based) Auxiliary materials used e.g. synthetic and natural polymers, inorganic materials, semiconductors, carbon and metallic materials properties and applications of advanced materials (particularly nanomaterials) in the production of chemical sensors and biosensors Advanced manufacturing methods Sensors obtained by combining particular transduction and recognition methods Mathematical modeling of chemical sensor processes Suitable as a textbook for graduate and final year undergraduate students, and also for researchers in chemistry, biology, physics, physiology, pharmacology and electronic engineering, this bookis valuable to anyone interested in the field of chemical sensors and biosensors.
