摘　　要：制备了一种用于促黄体生成素(LH)电化学传感器的多壁碳纳米管/亚甲基蓝/金纳米颗粒(MWCNT/MB/AuNP)纳米复合材料。利用光学显微镜(OM)、扫描电子显微镜(SEM)和X射线能量色散谱仪(EDS)对制备的纳米复合材料进行形貌表征。采用方波伏安(SWV)法和循环伏安(CV)法对AuNP的催化能力、纳米复合材料合成的最优化比例和氧化还原性能进行测试;对利用纳米复合材料制备的LH电化学传感器进行SWV测试。实验结果表明该纳米复合材料具有良好的氧化还原性能;利用纳米复合材料制备的电化学传感器具有良好的重复性和较宽的线性范围,能够在3.5~140 mIU/mL浓度内进行LH的检测。该纳米复合材料可推广应用于其他类型电化学传感器的制备。Multi-walled carbon nanotube/methylene blue/gold nanoparticle(MWCNT/MB/AuNP)nanocomposites were prepared for electrochemical sensors of luteinizing hormone(LH). Optical microscope(OM), scanning electron microscope(SEM) and X-ray energy dispersive spectrometer(EDS) were used for morphology characterization of the prepared nanocomposites. Square wave voltammetry(SWV) and cyclic voltammetry(CV) were adopted to test the catalytic capability of AuNP, synthesis optimum proportion and redox property of the nanocomposites. The electrochemical sensor of LH prepared with the nanocomposites was tested by SWV. The experimental results show that the nanocomposites have good redox property. The electrochemical sensor prepared by the nanocomposites has good repeatability and wide linear range, and can detect LH in the concentration range of 3.5-140 mIU/mL. The nanocomposites can be widely used for the preparation of other kinds of electrochemical sensors.
