Abstract
Analyte sensing devices that include an electrochemical aptamer-based (E-AB) sensor integrated with an organic electrochemical transistor (OECT) for signal amplification are provided. The E-AB sensor has a three-electrode setup that includes an aptamer-functionalized working electrode, an independent reference electrode, and a counter electrode composed of a mixed ionic-electronic conductive polymer. In the sensors, the working electrode simultaneously serves as a gate electrode for an OECT, while the mixed ionic-electronic conductive polymer also acts as the transistor channel of the OECT. This integrated device design retains the features of both the E-AB sensor and the OECT, thereby enabling electrochemical measurements to be carried out by the E-AB sensor, while simultaneously monitoring changes in the in-plane conductivity of the OECT channel.
