掺硼碳纳米管（BCNT）作为一种新型碳纳米材料具有较高的催化活性。研究了基于 BCNT 修饰电极的二氢烟酰胺腺嘌呤二核苷酸 (NADH) 的电分析。与裸露的玻璃碳（GC）和碳纳米管（CNT）/GC电极相比，BCNT/GC电极可以在较低的施加电位下对NADH进行高灵敏度的安培检测，并最大限度地减少表面污染。因此，BCNT 是用于检测 NADH 的有用且有前途的材料，并且对于基于脱氢酶的电流生物传感器或其他分析应用具有吸引力。
Boron-doped carbon nanotubes (BCNTs) as a novel carbon nanomaterial have higher catalytic activity. Electroanalysis of dihydronicotinamide adenine dinucleotide (NADH) based on the BCNTs modified electrode has been investigated. Comparing with the bare glassy carbon (GC) and carbon nanotubes (CNTs)/GC electrodes, the BCNTs/GC electrode allowed highly sensitive amperometric detection of NADH at the lower applied potential, and minimization of surface contamination. Therefore, BCNTs are useful and promising material for the detection of NADH and are attractive for dehydrogenase-based amperometric biosensor or other analytical applications.
