Here, we present a precision cancer nanomedicine based on Bi(2)S(3) nanorods (NRs) designed specifically for multispectral optoacoustic tomography (MSOT)/X-ray computed tomography (CT)-guided photothermal therapy (PTT). The as-prepared Bi(2)S(3) NRs possess ideal photothermal effect and contrast enhancement in MSOT/CT bimodal imaging. These features make them simultaneously act as "satellite" and "precision targeted weapon" for the visual guide to destruction of tumors in vivo, realizing effective tumor destruction and metastasis inhibition after intravenous injection. In addition, toxicity screening confirms that Bi(2)S(3) NRs have well biocompatibility. This triple-modality-nanoparticle approach enables simultaneously precise cancer therapy and therapeutic monitoring.
在这里,我们提出了一种基于 Bi(2)S(3)纳米棒(NRs)的精准癌症纳米医学,专门设计用于多谱光声断层扫描(MSOT)/X 射线计算机断层扫描(CT)引导的光热治疗(PTT)。所制备的 Bi(2)S(3) NRs 在 MSOT/CT 双模式成像中具有理想的光热效应和对比增强。这些特性使它们能够同时作为体内肿瘤破坏的可视引导的“卫星”和“精准靶向武器”,实现在静脉注射后有效破坏肿瘤和抑制转移。此外,毒性筛选证实 Bi(2)S(3)NRs 具有良好的生物相容性。这种三模态纳米颗粒方法能够实现精准癌症治疗和治疗监测。
