Abstract: This work is devoted to the development and optimization of thick-film ion-selective organic electrochemical transistors, using the determination of potassium as a model system. The sensor has been fabricated through a simple and low-cost process using paper as a substrate. A conducting polymer channel made of PEDOT:PSS was functionalized with an ion-selective membrane. Therefore, unlike conventional gate-sensitive systems, channel functionalization was evaluated. The analytical performance shows outstanding sensitivity, with values up to 2585 μA/dec, which is more than 20 times higher than the values reported up to date for similar systems. Moreover, the applicability of this sensor has been successfully tested in artificial serum.
