Recent progress of all solid state ion selective electrode

Abstract

All solid state ion selective electrodes (ISE) is a significant research orientation in the study of potentiometric sensors. With the development of science, traditional liquid junction ISEs exhibit many disadvantages. The study of all solid state ISE has been attracted more and more attention in recent decade. They have been applied in so many fields, such as clinical test, environment monitoring and industry analysis. According to the different ion electron transfer principle of all solid state transducer, all solid state ISEs are classified into three types: double layer capacitance all solid state ISE, redox capacitance all solid state ISE, and double layer and redox mixed capacitance all solid state ISE. In this mini-review, the progress of the above three types of all solid state ISE were introduced and summarized. Meanwhile, the responding mechanism of every type all solid state ISE was discussed. The development tendency of all solid state ISE was also predicted.
