Potentiometric sensors: Practical examples

This book is presented as support material for undergraduate and graduate students in chemical sciences. It is a brief introduction to potentiometric sensors, especially those that incorporate biological material (biosensors), in this case amperiometric. Ion-selective electrodes are explained and the biosensors used in the analysis of drugs, detection of pesticides, fertilizers and in the analysis of food additives are exemplified. Likewise, constructions of selective electrodes to several ions and their most significant response parameters are shown.
