Tumor treatment composite nano material and preparation method thereof

Abstract

The invention discloses a tumor treatment composite nano material which is characterized by being prepared from the following raw materials in parts by weight: 3-5 parts of silver sulfide quantum dots, 4-6 parts of silver selenide quantum dots, 1-2 parts of hyperbranched polytetrahydrofuran and 1-2 parts of epoxy alkoxy silicon modified bis (2-aminophenyl) disulfide. The invention also discloses apreparation method of the tumor treatment composite nano material. The tumor treatment composite nano material disclosed by the invention has the characteristics of good stability, long in-vivo circulation time, small toxic and side effects and the like, has a good drug slow release effect, has good selectivity on tumor cells, and does not have obvious systemic toxicity.

Description

technical field

[0001] The invention relates to the technical field of medical materials, in particular to a composite nanomaterial for tumor treatment and a preparation method thereof. Background technique

[0002] Chemoradiotherapy is the main method for clinical treatment of cancer, especially advanced cancer, and is an effective systemic treatment. However, the traditional chemoradiotherapy drugs and administration methods have the disadvantages of non-specific recognition of chemoradiotherapy drugs, which can easily damage normal cells and tissues, and even cause systemic poisoning. Moreover, the efficiency of drug uptake by tumor cells is low, and repeated administration can easily cause tumors. Cells develop drug resistance and other shortcomings.

[0003] In recent years, nano drug carriers have been widely used in the selective delivery of anticancer drugs due to their long blood circulation time and high passive tumor targeting efficiency. At present, the nano-dr...
