Impedimetric D-Xylose and D-Arabinose sensors was development from composite electrodes of graphite and histological paraffin, modified with functionalized multi-walled carbon nanotubes (FMWCNTs) based on molecular imprinted poly-o-phenylenediamine (poly-o-PD). The contribution of this work was not only the development of a D-xylose and D-Arabinose MIP impedimetric sensor with good performance, but also the electrodeposition method for FMWCNTs onto surface of graphite composites electrodes with ease of control and reproducibility of the electrodeposition process. The sensors were characterized by cyclic voltammetry (CV), electrochemical impedance spectroscopy (EIS), field emission gun scanning electron microscopy (FEG-SEM) and RAMAN spectroscopy. The MIPs sensors for the pentoses have good selectivity, sensitivity in the concentration range of 1.0 × 10 −11 to 1.0 × 10 −10 mol l −1 with limit of detection (LOD) of 4.50 × 10 −12 mol l −1...

基于电沉积碳纳米管和分子印迹聚邻苯二胺的戊糖酶阻抗传感器

阻抗式D-木糖和D-阿拉伯糖传感器是由石墨和组织石蜡的复合电极开发的，并基于分子印迹聚邻苯二胺（poly-o-PD）修饰了功能化的多壁碳纳米管（FMWCNT）。这项工作的贡献不仅在于开发具有良好性能的D-木糖和D-阿拉伯糖MIP阻抗传感器，而且是FMWCNTs在石墨复合材料电极表面上的电沉积方法，具有易于控制和电沉积过程可重复性的特点。通过循环伏安法（CV），电化学阻抗谱（EIS），场发射枪扫描电子显微镜（FEG-SEM）和RAMAN光谱对传感器进行了表征。戊糖的MIPs传感器具有良好的选择性，灵敏度在1的浓度范围内。
