纤维基有机电化学晶体管葡萄糖传感器的制备及性能研究
Preparation and Performance Study of Fiber-based Organic Electrochemical Transistor Glucose Sensor
摘要
Abstract
Fiber-based organic electrochemical transistors have broad application prospects in the fields of wearable electronic devices and biosensors due to the advantages of being flexible and wearable,low working voltage,high sensitivity,and good biocompatibility.In this study,cotton fiber was used as the raw material for electrodes,and graphene(Gr)and poly(3,4-ethylenedioxythiophene)-sodium polystyrene sulfonate(PEDOT∶PSS)were used to modify the fiber surface to form a layer of PEDOT∶PSS/Gr film on the fiber surface.The resistance of the poly(3,4-ethylenedioxythiophene)-sodium polystyrene sulfonate/graphene/fiber(PEDOT∶PSS/Gr/fiber)was as low as 60 Ω/cm.An organic electrochemical transistor device with stable output performance and high sensitivity was constructed by PEDOT∶PSS/Gr/fiber,and showed good linear response to glucose detection in the range of 1 pmol/L—10 µmol/L,with a detection limitation of 1 pmol/L.In addition,it is demonstrated that the sensor can resist interference from uric acid,ascorbic acid,and common metal ions(K+,Na+,Mg2+),which are common interferences in body fluids.The recovery rate was 87.2%—110%when used to detect saliva samples.This study can provide some technical support for non-invasive detection of blood glucose in diabetes.关键词
