Description
Technical Field
The invention relates to the technical field of nano composite materials, in particular to a preparation method of a copper selenide nano composite material with an excellent photo-thermal effect.

Cancer is one of the major diseases seriously harming human health globally, more than 800 million people die every year in the world according to data published by the world health organization, and new cancer cases are continuously appeared every year, and the number is expected to increase to 2000 or more ten thousand in 2030. Therefore, research on diagnosis and treatment of tumors is urgent. In order to solve the problem, the traditional Chinese medicine composition can be used as a novel cancer treatment method for adjuvant therapy, such as photodynamic therapy, photothermal therapy and the like. The main principle of photothermal therapy is that photo-thermal agents are used to convert light energy into heat to kill cancer cells, so that the nano composite material with good photothermal property has great significance for the research of cancer therapy.
At present, the preparation of the photo-thermal agent mostly has the defects of complex preparation process, high toxicity of a precursor, long reaction period, low photo-thermal conversion efficiency and the like, and most of the preparation of the metal selenide nano composite material adopts a hydrothermal method, namely, reactants are dissolved in a specific solvent, and the required selenide nano composite material is synthesized in a high-pressure reaction kettle at high temperature and high pressure. Most of the selenide nano-composite materials prepared by the method have the defects of complex preparation process, high cost, difficult regulation and control of product size, poor dispersion performance, easy agglomeration and the like.
Copper selenide nanoparticles, a transition metal chalcogenide nanomaterial, are of greater interest due to their p-type nature, high carrier concentration, possibility of optical bandgap tuning, and lower toxicity. In addition, most importantly, due to surface plasmon resonance absorption caused by the lack of copper ions, copper selenide has strong absorption in a near infrared region and high photothermal conversion efficiency, so that the copper selenide becomes a potential photothermal therapeutic agent. Most of the existing common preparation methods of copper selenide nanoparticles are a hydrothermal method and a microwave method, and the methods have the defects of complex operation and high cost.
ZIF is a kind of MOF material formed by crosslinking of metal ions such as Zn and Co with imidazole ligands through coordination bonds, as a kind of zeolite imidazole-type metal-organic framework. ZIF-67 is one of ZIFs, and the synthesis of the ZIF-67 can obtain the required application performance through the selection of metal ions and organic ligands.
