Embodiment 1

[0027] Example 1 Synthesis of trypsin-doped flower-like nanomaterials

[0028] Synthesis steps of trypsin-doped flower-like nanomaterials:

[0029] 1. Prepare 0.02, 0.10, 0.50, 1.00, 2.00, 3.00 mg / mL trypsin phosphate buffer solution (KCl, NaCl, NaCl, 2 HPO 4 12H 2 O, KH 2 PO 4 concentration of 0.1 mol / L, pH 7.40) and 0.12 mol / L copper sulfate pentahydrate solution.

[0030] 2. Take 4.5 mL of the protein solution in step 1 into a centrifuge tube, add 0.030 mL of the copper sulfate solution obtained in step 1, mix well, and place it in a 25°C water bath for 72 hours of constant temperature reaction.

[0031] 3. Wash the product obtained in step 2 with 10 mL of deionized water, and then separate the product by centrifugation. Repeat the washing process 3 times. The washed product was dried under vacuum at room temperature for 5 hours.

Description

technical field [0001] The invention belongs to the technical field of preparation of organic-inorganic composite materials, relates to nanomaterials, in particular to a protein-doped organic-inorganic hybrid flower-like nanomaterial and a preparation method thereof. Background technique [0002] Due to the special properties of large specific surface area, nanomaterials have broad application prospects in the fields of light, electricity, magnetism, chemistry and life sciences. Organic-inorganic hybrid nanomaterials are the fourth generation of new materials after single-component materials, composite materials and functionally graded materials. The controllable properties of molecules and atoms have gradually become one of the most promising research directions in materials science. Because it introduces different inorganic elements and organic ligands or polymers into the system, the material not only has the relevant properties of the inorganic active center or organic ...
