Monitoring of Glucose in Beer Brewing by a Carbon Nanotubes Based Nylon Nanofibrous Biosensor

Figure 3

Cyclic voltammetry of glucose at a glassy carbon electrode coated with (a) NFM with GOX immobilized; (b) NFM/CNT with GOX free in solution; (c) NFM/CNT with GOX immobilized. Experiment: 25.2 mM D-glucose, 100 μM ferrocene methanol, and Britton-Robinson buffer, 400 mM, pH 5. Detection was performed at 100 mV s⁻¹ scan rate. A full characterization of anodic peak current versus the scan rate and evaluated diffusion coefficients are reported in Supporting Information (Table SI 1 and Figure SI 1).
