Graphene Nanoribbons/Manganese Oxide Nanocomposite Modified Electrode for Detection of Antimicrobial Drug Nitrofurantoin

Figure 9

(a) The repeatability of the GNR/MnO₂ modified electrode was tested by five repeated measurements in freshly prepared 0.1 M PBS containing 10 µM NFT; (b) the long-term stability of the modified electrode during the analysis of NFT from 0 to 37 hr; (c) CVs of three different GNR/MnO₂ modified electrodes for the NFT reduction. (Inst figures of a–c show the percentage of response of the sensors during the repeatability, stability, and reproducibility measurements).
