It is notable that the results of the non-linear Michaelis-Menten curve and linear Burk diagram are in good agreement with each other. Moreover, Vmax/Km was calculated as a crucial indicator of enzyme catalytic efficiency, the results revealed a ratio of 1.0×10 -3 min -1 from the linear-Burk diagram which is close to that of the results of the non-linear Michaelis-Menten curve. It is notable, that the summary of the kinetic parameters of the oxidase-like Ce/Fe-bimetallic nanozymes provided from linear-Burk diagram and non-linear Michaelis-Menten curve are represented in Table .
