摘要：

Flexible organic electrochemical transistors (OECTs) are successfully used as high-performance enzyme biosensors, such as uric acid (UA) and cholesterol sensors. The sensitivity and selectivity of the sensors can be simultaneously enhanced by co-modifying the gate electrodes with positively/negatively charged bilayer polymer films and enzymes. These OECT-based UA sensors are successfully utilized for non-invasive UA detection in human saliva. (Figure Presented). © 2014 Wiley-VCH Verlag GmbH & Co. KGaA.
