Flexible organic electrochemical transistors for highly selective enzyme biosensors and used for saliva testing.
ADVANCED MATERIALS(2015)
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.
