Abstract

We explore and contrast the electroanalytical performance of a commercially available CVD grown graphene electrode with that of edge- and basal-plane pyrolytic graphite electrodes constructed from highly ordered pyrolytic graphite for the sensing of biologically important analytes, namely β-nicotinamide adenine dinucleotide (NADH) and uric acid (UA). We demonstrate that for the analytes studied here, in the best case, the electroanalytical performance of the CVD-graphene mimics that of edge plane pyrolytic graphite, suggesting no significant advantage of utilising CVD-graphene in this context.

摘要

我们探索并对比了一种商业 CVD 生长石墨烯电极与由高定向热解石墨制备的边缘和基面热解石墨电极在生物重要分析物（即β-烟酰胺腺嘌呤二核苷酸（NADH）和尿酸（UA））检测方面的电化学性能。我们证明，对于这里研究的分析物，在最佳情况下，CVD-石墨烯的电化学性能模拟了边缘平面热解石墨的性能，这表明在这种情况下利用 CVD-石墨烯并没有明显的优势。
