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

Figure 7

(a) CVs were recorded using a GNR-MnO₂ modified electrode with different concentration of NFT from 10 nM to 1,000 µM in 0.1 M PBS at the scan rate of 50 mV/s; (b) calibration graph was made between the concentration of NFT vs. reduction peak currents.
