Embodiment

[0030] A kind of Zn that can be used for the detection of glucose colorimetry 3 V 3 o 8 The hydrothermal synthesis method of microsphere, it comprises the following steps:

[0031] 1) Weigh 0.4g Zn(CH 3 COO) 2 2H 2 O, 0.4g anhydrous Na 2 SO 4 , 0.4g glycine, 1g hexadecyltrimethylammonium bromide, mixed into 60mL deionized water, stirred at 600 r / min at room temperature for 30min to form solution A; then weighed 0.42g Na 3 VO 4 12H 2 O and 0.42g ammonium carbonate were mixed and added to 6mL deionized water, and stirred at 600 r / min for 30min at room temperature to form solution B;

[0032] 2) Slowly add solution B obtained in step 1) to solution A, stir at 600 r / min for 30 minutes to make it fully mixed, place the obtained mixed solution in a reaction kettle, and react at 180°C for 24 hours;

[0033] 3) Cool to room temperature after the reaction, centrifuge at 8000 r / min for 10 min, remove the supernatant, wash the precipitate with deionized water and ethanol for 3 to...

Abstract

The invention discloses a Zn that can be used for glucose colorimetric detection 3 V 3 o 8 The hydrothermal synthesis method of microsphere, it is respectively with Zn(CH 3 COO) 2 2H 2 O and Na 3 VO 4 12H 2 O is the source of zinc and vanadium. By adding CTAB, glycine, and sodium sulfate as surfactants, using ammonium carbonate to adjust the pH value, the microspherical Zn 3 V 3 o 8 . Gained microspherical Zn of the present invention 3 V 3 o 8 It has the advantages of good dispersion, high catalytic performance, good stability, etc., and has peroxidase activity, which can be used for visual colorimetric detection of glucose, and the detection limit of glucose is as high as 9.33×10 ‑7 M, and has a wide linear range.

Description

technical field [0001] The invention belongs to the field of preparation of nanometer functional materials, in particular to a kind of Zn for colorimetric detection of glucose mimic enzyme 3 V 3 o 8 Hydrothermal Synthesis of Microspheres. Background technique [0002] The high efficiency and specificity of natural enzyme catalysis make it widely used in biosensing and disease treatment. However, most of natural enzymes are proteins with supramolecular structure, which leads to high cost, low stability, and difficulty in preservation of natural enzymes. The application and development of natural enzymes are largely restricted. Mimetic enzyme is a kind of artificially synthesized catalyst, which not only makes up for the disadvantages of natural enzymes, but also has high catalytic activity while maintaining the specificity of natural enzymes. Therefore, by studying the structure and active center of natural enzymes, designing artificial mimic enzymes with similar activiti...
