Abstract
Organic electrochemical transistors (OECTs) show promising applications in various chemical and biological sensors. The advantages of OECT-based sensors include low cost, easy fabrication, low operational voltage, mechanical flexibility and good biocompatibility. In this paper, we report three high-performance OECT-based sensors, including diatom, glucose and chemical oxygen demand sensors. Various gate electrodes, including Au, TiO2 nanotube arrays and Pt nanoparticles modified TiO2 nanotube arrays, have been selected and modified according to different demands. The sensing mechanisms and the perspective are described. In terms of the diverse materials selection and easy surface modification of the gate electrodes, it is expected that these kinds of OECT-based sensors may have more important applications in chemical and biological sensing.
