Embodiment 1

[0078] Step (1): Mix 1.25mmol n-tetrabutyl titanate with 16mL ethylene glycol and stir to form solution A; mix 1.25mmol manganese sulfate monohydrate with 4mL ethylenediamine and stir to form solution B; Under stirring, the above solution A and solution B are completely mixed to form solution C;

[0079] Step (2): Slowly add 5mL of ultrapure water dropwise to the above solution C under vigorous stirring, then transfer it to a 50mL stainless steel autoclave with a polytetrafluoroethylene liner, and react at 200°C for 24h After that, cool down to room temperature naturally. The product was collected by centrifugation and washed several times with ethanol and water to remove impurities. Finally, a light yellow powder is obtained by drying in a vacuum oven, which is two-dimensional manganese titanate nanosheets.

Embodiment 2

[0087] Compared with Example 1, the main difference is that the solvothermal temperature is 150° C., and the solvothermal time is 18 hours (the solvothermal temperature is reduced, and the solvothermal time is reduced).

[0088] Step (1): Mix 1.25mmol n-tetrabutyl titanate with 16mL ethylene glycol and stir to form solution A; mix 1.25mmol manganese sulfate monohydrate with 4mL ethylenediamine and stir to form solution B; Under stirring, the above solution A and solution B are completely mixed to form solution C;

Embodiment 3

[0091] Compared with Example 1, the main difference is that the solvothermal temperature is 250° C., and the solvothermal time is 30 h (the solvothermal temperature increases and the solvothermal time increases).

[0092] Step (1): Mix 1.25mmol n-tetrabutyl titanate with 16mL ethylene glycol and stir to form solution A; mix 1.25mmol manganese sulfate monohydrate with 4mL ethylenediamine and stir to form solution B; Under stirring, the above solution A and solution B are completely mixed to form solution C;

[0093] Step (2): Slowly add 5mL of ultrapure water dropwise to the above solution C under vigorous stirring, then transfer it to a 50mL stainless steel autoclave with a polytetrafluoroethylene liner, and react at 250°C for 30h After that, cool down to room temperature naturally.

Abstract

The invention belongs to the technical field of anti-cancer nanomaterials, and provides a manganese titanate nanomaterial, which has simulated enzyme activity and can kill cancer cells based on the simulated enzyme activity and cascade reactions of various simulated enzyme activities, thereby solving the problem of traditional chemical kinetics. Chemodynamic Therapy (CDT) has many defects such as insufficient anticancer ability and difficulty in killing cancer cells.

Description

technical field [0001] The invention belongs to the technical field of anti-cancer nano material development, and relates to the use of a manganese titanate nano material for anti-cancer based on the simulated enzyme activity. Background technique [0002] Cancer, also known as malignant tumor, refers to a disease caused by the abnormal proliferation of cells, which has the property of invading other tissues or organs of the body, and the related mechanisms controlling cell proliferation are out of balance. For humans, there are currently more than one hundred known types of cancer, and it has long been considered an incurable disease, which greatly endangers the safety of human life and reduces the quality of human life. Current clinical treatments for cancer include surgery, chemotherapy, and radiotherapy. Surgical treatment can only remove the cancer tissue in the early stage, but large area recurrence and metastasis may still occur several years after the operation. Ch...
