Kaolinite composite diagnostic and therapeutic agent and preparation method and use thereof
The kaolinite composite diagnostic and therapeutic agent uses modified kaolinite as a carrier and is loaded with carbon nitride quantum dots and doxorubicin. The present disclosure provides a preparation method of the kaolinite composite diagnostic and therapeutic agent, including the following steps: S1: preparing the modified kaolinite by subjecting the pharmaceutical grade kaolinite to intercalation, exfoliation, and immersion wet etching; S2: subjecting the modified kaolinite and a carbon nitride quantum dot solution to ultrasonication, drying, and grinding to obtain a kaolinite composite containing the carbon nitride quantum dots; and S3: dissolving the doxorubicin in the dark, adding dissolved doxorubicin into the kaolinite composite containing the carbon nitride quantum dots, shaking in the dark for a period of time, and washing and drying to obtain the diagnostic and therapeutic agent containing the carbon nitride quantum dots and the doxorubicin..
