Abstract

The invention discloses a bio-safety carbon quantum dot-loaded adriamycin complex. A preparation method of the bio-safety carbon quantum dot-loaded adriamycin complex comprises the following steps: (1) mixing milk and deionized water according to the volume ratio of (5-6):(4-5), then putting at a temperature of 160-200 DEG C and heating for 2-4 hours; (2) cooling to a room temperature, centrifuging for 30-45 minutes under 10000-12000 r / min and taking supernatant liquid; (3) filtering with a filter membrane to obtain a carbon quantum dot solution; (4) preparing a carbon quantum dot aqueous solution; (5) preparing an adriamycin aqueous solution; (6) mixing the carbon quantum dot aqueous solution, the adriamycin aqueous solution and a PBS solution and preparing a mixed solution with pH being equal to 7.4; (7) performing light-shading reaction and dialysis to prepare. The preparation method is simple, the adriamycin load rate is high, the prepared complex is high in bio-safety, the killing efficiency of tumor cells is significantly improved, the killing efficiency of normal cells is significantly reduced, and the bio-safety carbon quantum dot-loaded adriamycin complex can be used for tumor disease treatment.

Description

technical field [0001] The invention belongs to the technical field of medicine, and in particular relates to a biosafety carbon quantum dot-loaded doxorubicin complex and its preparation method and application. Background technique [0002] Cancer is one of the important diseases that threaten human life and health. Millions of people die of cancer every year. The treatment of cancer is a topic that medical workers and researchers continue to explore. In addition to surgical treatment, chemotherapy is an important treatment method. There are many kinds of chemotherapeutic drugs for different types of cancer. Adriamycin is a kind of spectrum anti-cancer drug, which has a killing effect on a variety of tumor cells. It is widely used clinically in acute lymphoblastic leukemia, lymphoma, breast cancer, ovarian cancer, and lung cancer. , gastric cancer, liver cancer, head and neck squamous cell carcinoma, etc. However, due to the single way of uptake of doxorubicin by tumor ce...
