A smart nanoprobe based on luminescent terbium metal-organic framework coated gold nanorods for monitoring and photo-stimulated combined thermal-chemotherapy

Real-time monitoring and accurate treatment are of great significance for reducing the side effects during the cancer therapy.In this work,we rationally prepared a smart nanoprobe based on core-shell terbium metal-organic gramework(MOF)with highly effective photothermal conversion capacity and drug release efficiency under near-infrared light irradiation for real-time fluorescence imaging-guided multimodal therapy.The nanoprobe can achieve prominent photothermal therapy and controllable drug release,act as a fluorescence thermometer,and also real-time feedback of temperature is expected to be achieved.At the same time,the two-photon ligand design significantly improves the tissue penetration ability of the nanoprobe.Our work is expected to provide a reference for precise treatment and real-time monitoring of tumors and at the same time provide new ideas for the formulation of individualized treatment plans.
