Embodiment 1
[0040] A method for rapid colorimetric analysis of total antioxidant capacity based on the enzymatic activity of MnCo@C NCs, including the following steps:
[0041] (1) Preparation of MnCo@C NCs composite nanomaterials:
[0042] (1.1) Manganese acetate and PVP (K-30) are dispersed in a mixed solution of ethanol and water and stirred, then, an aqueous solution of potassium cobalt cyanide is added, the mass ratio of manganese acetate and PVP is 1:5, the mole of Mn and Co The ratio is 1:1, and the MnCo precursor is obtained by incubating at room temperature;
[0043] (1.2) redispersing the prepared MnCo precursor into an aqueous solution, then adding an aqueous solution of dopamine, and the mass ratio of dopamine to MnCo precursor is 1:1 to obtain;
[0044] (1.3) The MnCo@C NCs obtained in step (1.2) are obtained by pyrolysis at high temperature.
[0045] like figure 1 The electron microscope imaging analysis of MnCo@C NCs shows that the MnCo@C NCs have a core-shell structure ...
Embodiment 2
[0056] Wherein, in step (1), the mass ratio of manganese acetate to PVP is 1:10, and the molar ratio of Mn to Co is 1:3, and incubated at room temperature to obtain MnCo precursor; the mass ratio of dopamine to MnCo precursor is 1:3.
[0057] The rest are the same as in Example 1.
[0058] It should be noted that the properties of the MnCo@CNCs prepared in Example 2 are the same as those of the MnCo@CNCs prepared in Example 1, and also have good oxidase-like activity.
[0059] It can be seen that the rapid colorimetric analysis method for total antioxidant capacity based on the oxidase-like activity of MnCo@C NCs composite nanomaterials of the present invention can be used to qualitatively and quantitatively detect AA concentration, and can analyze food according to linear regression equation. the TAC.
