Electrochemical methods of chemical analysis have been widely used for many years, most especially the trusty pH electrode and conductivity meter, but also in the mass-manufactured glucose test strips which place electrochemical measurements into the hands of non-scientists. The purpose of this volume is to address advances that will enable new measurement strategies in the future. Surveying research and development advances based on new methods, materials and devices that achieve improved electroanalytical performances, this collection encompasses chip-based systems, through nanodomain approaches and soft interfaces. This book is a vital resource for graduate students and professional analytical chemists.
