摘　　要：将磷酸胆碱接枝的聚(3,4—乙烯二氧噻吩)(EDOT-PC)作为导电聚合物主体与葡萄糖氧化酶共沉积到金(Au)片表面,制备出一种仿生导电高分子葡萄糖传感器。该传感器可实现对0.05~21 mmol/L的葡萄糖溶液的检测,且在存有牛血清蛋白(BSA)的葡萄糖磷酸盐缓冲液(PBS)里有着明显的电化学响应,表明具有良好的抗蛋白粘附性。该策略为柔性可穿戴汗液传感器的构建提供了新思路。A biomimetic conductive polymer glucose sensor is prepared by co-depositing the poly(3,4-ethylenedioxythiophene)grafted with phosphorylcholine(EDOT-PC)as the host of the conductive polymer and glucose oxidase on the surface of the gold(Au)sheet.The sensor can detect glucose solution of 0.05~21 mmol/L,and the sensor has good anti-protein adhesion,and has a good electrochemical response in glucose phosphate buffered saline(PBS)containing bovine serum albumi(BSA).This strategy provides a new idea for the construction of flexible wearable sweat sensors.
