Laboratory Methods in Dynamic Electroanalysis

Laboratory Methods in Dynamic Electroanalysis is a useful guide to introduce analytical chemists and scientists of related disciplines to the world of dynamic electroanalysis using simple and low-cost methods. The trend toward decentralization of analysis has made this fascinating field one of the fastest-growing branches of analytical chemistry. As electroanalytical devices have moved from conventional electrochemical cells (10-20 mL) to current cells (e.g. 5-50 mL) based on different materials such as paper or polymers that integrate thick- or thin-film electrodes, interesting strategies have emerged, such as the combination of microfluidic cells and biosensing or nanostructuration of electrodes.

This book provides detailed, easy procedures for dynamic electroanalysis and covers the main trends in electrochemical cells and electrodes, including microfluidic electrodes, electrochemical detection in microchip electrophoresis, nanostructuration of electrodes, development of bio (enzymatic, immuno, and DNA) assays, paper-based electrodes, interdigitated array electrodes, multiplexed analysis, and combination with optics. Different strategies and techniques (amperometric, voltammetric, and impedimetric) are presented in a didactic, practice-based way, and a bibliography provides readers with additional sources of information.

Provides easy-to-implement experiments using low-cost, simple equipmentIncludes laboratory methodologies that utilize both conventional designs and the latest trends in dynamic electroanalysis Goes beyond the fundamentals covered in other books, focusing instead on practical applications of electroanalysis
