Real-Time Sensing of Hydrogen Peroxide by ITO/MWCNT/Horseradish Peroxidase Enzyme Electrode

Figure 3

The amount of H₂O₂ reduced by 20 nM HRP (with guaiacol and amplex red as indicated) as a function of time. Figure was made by the absorption change of guaiacol and AR in PBS buffer solution (0.1 M, pH 7.0). Figure shows the initial slopes and theirs straight-line equations with the goodness-of-fits ().
