本文报道了一种基于氧化铁修饰的垂直取向氧化锌纳米棒（Fe2O3- znrs）的非酶促葡萄糖传感器场效应晶体管（FET）。与传感性能较差的ZnO基非酶促葡萄糖传感器相比，Fe2O3修饰ZnO具有优异的电催化性质，显著提高了制备的非酶促FET葡萄糖传感器的传感性能。在优化条件下，制备的非酶促FET传感器对葡萄糖检测具有良好的催化活性，线性范围达18 mM，检测限低至12 phi，选择性好，重复性好，长期稳定性好。此外，制造的FET传感器检测新鲜抽取的小鼠全血和血清样本中的葡萄糖。所开发的FET传感器在实际样品中具有实际应用价值，并且基于溶液的合成工艺具有成本效益。(C) 2017 Elsevier B.V.版权所有
Herein, we report a non-enzymatic glucose sensor field-effect transistor (FET) based on vertically-oriented zinc oxide nanorods modified with iron oxide (Fe2O3-ZNRs), Compared with ZnO-based non-enzymatic glucose sensors, which show poor sensing performances, modification of ZnO with Fe2O3 dramatically enhances the sensing behavior of the fabricated non-enzymatic FET glucose sensor due to the excellent electrocatalytic nature of Fe2O3. The fabricated non-enzymatic FET sensor showed excellent catalytic activity for glucose detection under optimized conditions with a linear range up to 18 mM, detection limits down to-12 phi, excellent selectivity, good reproducibility and long-term stability. Moreover, the fabricated FET sensor detected glucose in freshly drawn mouse whole blood and serum samples. The developed FET sensor has practical applications in real samples and the solution-based synthesis process is cost effective. (C) 2017 Elsevier B.V. All rights reserved.
