摘要："Prostate cancer (PCa) is one of the most common cancer types. Early detection of PC offers the best chance of successful treatment. A noninvasive, image-guided therapy mediated by targeted nanoparticles (NPs) has the potential to improve the efficacy and safety of cancer therapies. Herein, we report a sonosensitive nanoparticle modified with anti-PSMA (prostate-specific membrane antigen) antibodies to activate target prostate tumors. These nanoparticles (PFP@IR780@PTX@liposome NPs) were co-loaded with the chemotherapeutic agent docetaxel and the sonosensitizer IR780, as well as phase-changeable perfluorocarbon (PFC) liquids. The liquid-gas phase change could be induced by low-intensity focused ultrasound (LIFU) in vitro. We found that the PFP@IR780@PTX@liposome NPs can specifically accumulate in prostate tumors after LIFU irradiation, as monitored by ultrasound and photoacoustic imaging. Meanwhile, docetaxel was controllably released from the nanoparticles to achieve enhanced chemotherapeutic therapy in vivo. These sonosensitive phase-changeable NPs can visually treat prostate cancers effectively and have a clinical potential."
