<p>Figure 3. Response of enzyme-functionalized GFETs to two nitriles.</p> <p><br></p> <p>Figure 3a. Normalized response of wild-type QueF and QueF-Y5Y fusion protein to concentrations of preQ₀ to 500nM. Gray vertical lines represent approximate timings for analyte addition. Arrowed symbols: ● = sensor wash in phosphate buffer, ◆ = addition of 4 µM NADPH, ■ = addition of 1 M substrate. GFET conditions: <em>V</em>_g: 500 mV, <em>V</em>_d: 5 mV.</p> <p><br></p> <p>Figure 3a.
