There is an urgent need for electrochemical sensor materials that exhibit electrochemically compliant properties while also retaining high durability under physiological conditions. Herein, we demonstrate a novel strip-style electrochemical sensor using reduced graphene oxide (rGO) and poly(ethylene dioxythiophene)/poly(styrene sulfonic acid) (PEDOT/PSS) nanocomposite films. The fabricated rGO-PEDOT/PSS sensor with and without nafion has shown an effective electrochemical response for both selectivity and sensitivity of the serotonin (5-hydroxytryptamine, 5-HT) neurotransmitter. The developed high-performance hybrid graphene/conducting polymer strip sensors are likely to find applications as chip electrochemical sensor devices for patients diagnosed with Alzheimer's disease.
迫切需要一种电化学传感器材料，该材料既要展现出符合电化学要求的特性，又要在生理条件下保持高耐久性。在此，我们展示了一种使用还原氧化石墨烯（rGO）和聚（3,4-乙撑二氧噻吩）/聚（苯乙烯磺酸钠）（PEDOT/PSS）纳米复合膜的新型条状电化学传感器。制备的含和不含全氟磺酸离子交换膜的rGO-PEDOT/PSS传感器对血清素（5-羟色胺，5-HT）神经递质的选择性和灵敏度均表现出有效的电化学响应。所开发的高性能混合石墨烯/导电聚合物条状传感器有望作为芯片电化学传感器设备应用于被诊断患有阿尔茨海默病的患者。
