The invention discloses a preparation method of a traceable anti-tumor drug based on a carbon dot and a medicament thereof, and the specific steps are as follows: Step 1: mixing a carbon point with a CPT ethanol solution to obtain a first mixed solution, and then to the first mixture An ethanol solution is added to the solution and stirred. After the stirring is completed, the supernatant is separated and the supernatant is separated to obtain a solid substance. The solid substance is washed with ethanol, added to the second mixed solution, and dried in an oven to obtain a solid powder. It is the finished product. The invention combines the anticancer drug camptothecin on the carbon spot, and successfully obtains a "carbon point-anticancer drug" complex with good water solubility and high drug loading rate, and the "carbon point-anticancer drug" complex has The killing efficiency of cancer cells is high and traceable. |
