Latest Patents

Xudong Ji holds a patent for an "Organic electrochemical transistor as an on-site signal amplifier for electrochemical aptamer-based sensors." This invention provides analyte sensing devices that include an electrochemical aptamer-based (E-AB) sensor integrated with an organic electrochemical transistor (OECT) for signal amplification. The E-AB sensor features a three-electrode setup, which includes an aptamer-functionalized working electrode, an independent reference electrode, and a counter electrode made of a mixed ionic-electronic conductive polymer. In this design, the working electrode also serves as a gate electrode for the OECT, while the mixed ionic-electronic conductive polymer acts as the transistor channel. This integrated device design retains the features of both the E-AB sensor and the OECT, enabling electrochemical measurements while monitoring changes in the in-plane conductivity of the OECT channel. Xudong Ji has 1 patent to his name.
