Sensitive electrochemical detection of NADH and ethanol at low potential based on pyrocatechol violet electrodeposited on single walled carbon nanotubes-modified pencil graphite electrode.

本研究首先利用电化学表面等离子共振（ESPR）技术研究了吡罗紫（PCV）的电沉积过程，随后将PCV作为氧化还原介体电沉积到单壁碳纳米管（SWCNTs）修饰的铅笔石墨电极（PGE）表面。由于SWCNTs与PCV的协同作用，PGE/SWCNTs/PCV电极在低电位（0.2 V vs. SCE）下对还原型烟酰胺腺嘌呤二核苷酸（NADH）氧...
