203 | Au@CD NPs | OXD | DAB | 42 | mM | 203 | the GOx-like activity of Au@CD was first investigated by using DAB as the chromogenic substrates and an absorbance at 460 nm as the quantitative referenced wavelength. As shown in Figure S5, the Michaelis–Menten constant (Km) for the Au@CD NPs was 42 mM, which was distinctly higher than that of glucose oxidase (about 4.87 mM). |
