Ion sensors based on organic transistors
This chapter presents the ion sensors which convert the activity of an ion dissolved in a solution into an electrical potential. This type of sensors is well-known and they are widely used in analytical chemistry and biochemistry. The use of organic polymers as active part of the ion sensors has led to a new way of research in these sensors. The chapter is divided into two parts: pH sensors and general ion sensors. The two parts are further divided based on the type of organic semiconductor used in the device fabrication: P3MT, PANI, PEDOT, etc. As a result of the organic electronic applications into the field of organic sensors, a wide variety of devices have been developed, for instance, ISOFET, OFET, EGOFET. For this reason, some applications of these devices have been explained for each organic semiconductor.
