Ion-Selective Electrode Reviews, Volume I focuses on the development, theory, and applications of selective electrochemical sensors. The book points at the widespread demand for methods of identifying ions in different branches of science, technology, and medicine. Containing the papers of authors who are experts in this discipline, the book proceeds by discussing the advancement in the research on the design of calcium ion-selective electrodes. Following this discussion is a chemical analysis of ion-sensitive field effect transistors and its corresponding applications to medicine. The paper also highlights the industrial applications of ion-sensitive electrodes and considers the measurement systems for industrial use. The book also points to the application of ion-selective electrodes to dental health, mineralized tissue programs, and inwater analysis. The text then closes by focusing on electrode development, particularly on the research on electrodes. The book is recommended for readers who are interested in doing research on ion-selective electrodes, particularly on their compositions and possible applications.
