采用电沉积法将葡萄糖氧化酶（GOx）和钯纳米颗粒共沉积到Nation增溶的碳纳米管（CNT）膜上。共沉积的Pd-GOx-Nafion CNT生物电极保留其生物催化活性，并提供酶促释放的H2 O2的有效氧化和还原，从而实现快速和灵敏的葡萄糖定量。Pd-GOx电沉积与Nafion增溶的CNT的组合提高了传感器的存储时间和性能。一个额外的Nafion涂层被用来消除常见的干扰物，如尿酸和抗坏血酸。所制备的Pd-GOx-Nafion CNT葡萄糖生物传感器表现出线性响应高达12 mM的葡萄糖和0.15 mM的检测限（S/N=3）。(c)2004 Elsevier B. V.保留所有权利。
Electrodeposition was used for the co-deposition of glucose oxidase (GOx) enzymes and palladium nanoparticles onto a Nation-solubilized carbon nanotube (CNT) film. The co-deposited Pd-GOx-Nafion CNT bioelectrode retains its biocatalytic activity and offers an efficient oxidation and reduction of the enzymatically liberated H2O2, allowing for fast and sensitive glucose quantification. The combination of Pd-GOx electrodeposition with Nafion-solubilized CNTs enhances the storage time and performance of the sensor. An extra Nafion coating was used to eliminate common interferents such as uric and ascorbic acids. The fabricated Pd-GOx-Nafion CNT glucose biosensor exhibits a linear response up to 12 mM glucose and a detection limit of 0.15 mM (S/N=3). (c) 2004 Elsevier B.V. All rights reserved.
