ABTS oxidation product yields catalyzed by (a) free MNPs, (b) free Mb, and (c) Mb-MNPs1mg conjugates. The corresponding comparative data for samples of Mb-MNPs5mg and Mb-MNPs10mg along with the respective free MNPs and free Mb controls are also shown as labeled in the x-axis. ABTS oxidation was carried out in PBS solution in the presence of hydrogen peroxide (1 mM) at 25 °C, pH 7.4.
