This invention discloses carbon nanodots, their preparation method, and their applications, relating to the field of carbon nanomaterials technology. The carbon nanodots are prepared by solvothermal treatment of nicotinamide, urea, and citric acid or its derivatives. The citric acid derivative is selected from citrate, citric acid hydrate, or citrate hydrate. This invention synthesizes carbon nanodots using nicotinamide as a precursor under solvothermal treatment, simultaneously integrating intrinsic bioactivity, efficient photothermal conversion capability, and red fluorescence imaging function. This multifunctional synergistic therapy overcomes the limitations of single-therapy approaches. Furthermore, the carbon nanodots provided by this invention exhibit extremely high biocompatibility.
