摘要

采用溶胶凝胶法在碳纳米纤维电极上制备了三维有序多孔结构的碳纤维掺杂纳米铂修饰电极,并检测过氧化氢氧化还原,从而构建了一种新型的H_2O_2生物传感器。通过循环伏安和计时电流等方法研究了该修饰电极的电化学特性,实验结果表明,该修饰电极对H_2O_2有良好的电催化作用,对H_2O_2的检测线性范围为3.0×10~(-8)~1.6×10~(-1)mol/L,检测限为2.0×10~(-8)mol/L(S/N=3);且传感器响应迅速、灵敏度高、重现性和稳定性好。
We reported a novel concept about 3D nano-micro structured biosensor,take hydrogen peroxide as an axample,it shows wide detection range,low detection limit Jong stability high reproducibility.Thus it has great chance to industrialize in the future..Here we put up with a novel non-enzymatic hydrogen peroxide sensor which was simply prepared by coating platinum nano-particles onto the carbon nano-fibers based on the Solid-Liquid-Gas Co-existent Boundary.This electrode shared the unique advantages of the good electro-catalytic activity and the high electric conductivity,large surface area and high porosity due to its three dimensional nano-structure.It applied in hydrogen peroxide detection,showed high sensitivity and low detection limit.The linear range was 3.0×10~(-8) ~3.6×10~(-1)mol/L and the detection limit was 2.0×10~(-8) mol/L(S/N =3).The hydrogen peroxide sensor also showed long-term stability.
