The preparation method of the PEG-CuMo2S3 nano material comprises the steps: mixing 1 to 7.2 parts by mass of copper acetate, 1 to 5 parts by mass of thioacetamide, 5 to 20 parts by mass of sodium molybdate, 100 to 500 parts by mass of PEG-400 and 100 to 500 parts by mass of deionized water, carrying out a hydrothermal reaction, separating a solid product from a reaction solution, and carrying out cleaning and drying so as to obtain the PEG-CuMo2S3 nano material. According to the preparation method of the PEG-CuMo2S3 nano material and the nano material, copper acetate, thioacetamide and sodium molybdate are adopted to synthesize Cu7.2S4 / MoS2, the Cu7.2S4 / MoS2 is directly loaded on PEG-400, the PEG-CuMo2S3 nano material is prepared, the preparation method is simple, the specific surface area of the product is high, the drug loading capacity is large, and drug treatment of cancers is facilitated.

Description

technical field [0001] The invention relates to nano functional materials, in particular to a PEG-CuMo 2 S 3 Preparation methods of nanomaterials and nanomaterials. Background technique [0002] The treatment of tumors is still a challenge today. Photothermal therapy and photodynamic therapy, as minimally invasive treatment methods in the field of nanomedicine, have attracted the attention of researchers. The hypoxia, overexpression of hydrogen peroxide, and excess glutathione in the tumor microenvironment are the starting point for researchers to treat tumor diseases today. In recent years, researchers have prepared a series of nano-platforms to regulate the tumor microenvironment by triggering the generation of oxygen and the depletion of glutathione to enhance the effect of photodynamic therapy. Cu 7.2 S 4 / MoS 2 A nanomedical material belonging to transition metal chalcogenides, which has strong absorption in the near-infrared region, can be used for photothermal t...
