Electrochemical Biosensors summarizes fundamentals and trends in electrochemical biosensing. It introduces readers to the principles of transducing biological information to measurable electrical signals to identify and quantify organic and inorganic substances in samples. The complexity of devices related to biological matrices makes this challenging, but this measurement and analysis are critically valuable in biotechnology and medicine. Electrochemical biosensors combine the sensitivity of electroanalytical methods with the inherent bioselectivity of the biological component. Some of these sensor devices have reached the commercial stage and are routinely used in clinical, environmental, industrial and agricultural applications. - Describes several electrochemical methods used as detection techniques with biosensors - Discusses different modifiers, including nanomaterials, for preparing suitable pathways for immobilizing biomaterials at the sensor - Explains various types of signal monitoring, along with several recognition systems, including antibodies/antigens, DNA-based biosensors, aptamers (protein-based), and more

The critically acclaimed guide to the principles, techniques, and instruments of electroanalytical chemistry-now expanded and revised Joseph Wang, internationally renowned authority on electroanalytical techniques, thoroughly revises his acclaimed book to reflect the rapid growth the field has experienced in recent years. He substantially expands the theoretical discussion while providing comprehensive coverage of the latest advances through late 1999, introducing such exciting new topics as self-assembled monolayers, DNA biosensors, lab-on-a-chip, detection for capillary electrophoresis, single molecule detection, and sol-gel surface modification. Along with numerous references from the current literature and new worked-out examples, Analytical Electrochemistry, Second Edition offers clear, reader-friendly explanations of the fundamental principles of electrochemical processes as well as important insight into the potential of electroanalysis for problem solving in a wide range of fields, from clinical diagnostics to environmental science. Key topics include: The basics of electrode reactions and the structure of the interfacial region Tools for elucidating electrode reactions and high-resolution surface characterization An overview of finite-current controlled potential techniques Electrochemical instrumentation and electrode materials Principles of potentiometric measurements and ion-selective electrodes Chemical sensors, including biosensors, gas sensors, solid-state devices, and sensor arrays

Principles of Polarography is a revised and extended version of an original Czech edition that appeared in 1962 at the Publishing House of the Czechoslovak Academy of Sciences in Prague. Based on a one-term course of lectures for third-year students of chemistry at the Charles University it brings the fundamental results of more than forty years' research in the field of polarography. The book contains 22 chapters and opens with a discussion of the principles of polarography. This is followed by separate chapters on polarizable electrodes used in polarography; charging current; influence of the resistance of the electrolyte on polarographic curves; migration and diffusion-controlled currents; and equation of a reversible polarographic wave. Subsequent chapters deal with reversible processes controlled by diffusion of complex ions; reversible reduction of organic substances; deposition of mercury ions; irreversible electrode processes; applications of limiting currents; polarographic curves for the formation of semiquinones and dimers; and catalytic hydrogen currents.

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.

In a real tour-de-force of scientific publishing, three distinguished experts here systematically deliver both the underlying theory and the practical guidance needed to effectively apply square-wave voltammetry techniques. Square-wave voltammetry is a technique used in analytical applications and fundamental studies of electrode mechanisms. In order to take full advantage of this technique, a solid understanding of signal generation, thermodynamics, and kinetics is essential. Not only does this book cover all the necessary background and basics, but it also offers an appendix on mathematical modeling plus a chapter on electrode mechanisms that briefly reviews the numerical formulae needed to simulate experiments using popular software tools.
