dc.description.abstract将DNA功能化多壁碳纳米管(MWCNTs)复合材料修饰于玻碳基底(GC)表面制得DNA-MWCNTs/GC电极,并在此基础上电沉积负载Pt纳米颗粒构建了一种新型无酶H2O2传感电极. 利用扫描电子显微镜(SEM)表征制得的修饰电极,同时通过循环伏安法和计时电流法研究了该传感电极的H2O2响应性能. 结果表明,该传感电极的H2O2检测在0.04 ~ 18.07 mmol·L-1浓度范围内成线性相关,检出限3.85 μmol·L-1(S/N = 3),且有良好的重现性、稳定性与选择性.zh_CN
dc.description.abstractThe DNA-multi-walled carbon nanotubes (MWCNTs)/glassy carbon (GC) electrode was prepared by modifying the DNA functionalized MWCNTs composite on a GC electrode. A novel non-enzymatic H2O2 sensing electrode was fabricated by electrodepositing Pt nanoparticles on the DNA-MWCNTs/GC electrode. The modified electrodes were characterized by scanning electron microscope (SEM). The response properties of the sensing electrode to H2O2 were investigated by cyclic voltammetry and chronoamperometry. The results indicated that the sensing electrode exhibited a good linear relationship between response current and H2O2 concentration in the range of 0.04 ~ 18.07 mmol·L-1 with a detection limit of 3.85 μmol·L-1 (S/N = 3), as well as excellent reproducibility, stability and selectivity.zh_CN
