摘要："Photothermal therapy (PTT), by converting light to thermal energy, has become a novel and noninvasive technique for tumor thermal ablation in clinical practice. However, as a result of phagocytosis of reticuloendothelial cells, current photothermal agents (PTAs) derived from exogenous materials suffer from incompetent tumor targeting and brief internal circulation time. The resulting poor accumulation of PTAs in the target area severely reduces the efficacy of PTT. In addition, the potential toxicity of PTAs, excessive laser exposure, and possibilities of tumor recurrence and metastasis following PTT are still intractable problems that severely influence patients' quality of life. Herein, a biomimetic pH-responsive nanoprobe was prepared via cancer cell membrane coating polydopamine (PDA)-CaCO3 nanoparticles (CPCaNPs) for photoacoustic (PA)/ultrasonic (US)/thermal imaging-guided PTT. When CPCaNPs targeted and infiltrated into the tumor's acidic microenvironment, the decomposed CO2 bubbles from homologous targeting CPCaNPs enhanced ultrasonic (US) signals obviously. At the same time, the PDA of CPCaNPs not only performed efficient PTT of primary tumors but also generated photoacoustic (PA) signals. In addition, an immune checkpoint pathway blockade was combined, which inhibited tumor recurrence and metastasis significantly and improved the immunosuppressive microenvironment after PTT to a large extent. Thus, these proposed biomimetic pH-responsive CPCaNPs provide a promising strategy for precise PTT immunotherapy under the intelligent guidance of PA/US/thermal imaging and show great potential for clinical translation."
