- 制备了三维花状氧化铜纳米材料及氧化铜(CuO)/还原氧化石墨烯(rGO)纳米复合材料,并利用SEM、TEM、XRD、Raman和XPS对合成的纳米材料进行了表征.将所制备的纳米材料应用于修饰电极构建扑热息痛生物传感器,实验结果显示:相比于氧化铜和还原氧化石墨烯的单一材料,纳米复合材料修饰的电极对检测扑热息痛具有较强的氧化还原能力,并且在浓度3.00～500 μmol/L范围内呈良好的线性关系,检出限为0.19 μmol/L(S/N=3).此外,该生物传感器用于测定实际样品的结果令人满意.
- Abstract:
- The 3D flowerlike CuO and CuO/reduced graphene oxide nanocomposite were prepared in this paper, the SEM, TEM, XRD, Raman and XPS were utilized to characterize the obtained nanomaterials. The as-prepared nanomaterials were employed to modify the electrodes for constructing the paracetamol biosensor, the results show that the hybrid modified electrode for detecting the paracetamol with excellent redox ability compared with single CuO or reduced graphene oxide, and in the range of 3.00-500 μmol/L for paracetamol concentration have a good linear relationship, the detection limit is 0.19 μmol/L(S/N=3). Moreover, this biosensor was employed to detect practical samples with satisfactory results.
