Precisely locating tumor site based on tumor-microenvironment-induced (TMI) multimodal imaging is especially interesting for accurate and efficient cancer therapy. In the present investigation, a novel TMI all-in-one nanoplatform, CuSNC@DOX@MnO2-NS, has been successfully fabricated for chemical and photothermal (Chem-PTT) therapy guided by multimodal imaging on tumor site. Here, the CuS nanocages with mesoporous and hollow structure (CuSNC) acting as nanocarriers provide high capacity for loading the anticancer drug, doxorubicin (DOX). The outer layer of the MnO2 nanoshell (MnO2-NS) acts as "gatekeeper" to control the DOX release until the nanoplatform arrives at the tumor site, where abundant glutathione and H+ decompose MnO2-NS into paramagnetic Mn2+. The magnetic resonance imaging and fluorescent imaging were then triggered to locate the tumor, which was further improved by photothermal imaging on account of the intrinsic property of CuSNC. Guided by the multimode imaging, the combination of chemical therapy upon DOX and photothermal therapy upon CuSNC exhibits eminent efficiency on tumor ablation. The nanoplatform exhibits biocompatibility to avoid unwanted harm to normal tissues during trans-shipment in the body. The investigation thus develops a cost-effective TMI nanoplatform with facile preparations and easy integration of Chem-PTT treatment capabilities guided by multimodal imaging for potential application in precise therapy.

肿瘤微环境诱导的多合一纳米平台用于癌症的多模态成像引导化学和光热疗法。

基于肿瘤微环境诱导(TMI)多模态成像的精确定位肿瘤部位对于准确,高效的癌症治疗尤为有趣。在本研究中,已成功制造了一种新型TMI多合一纳米平台CuSNC @ DOX @ MnO2-NS,用于在肿瘤部位进行多峰成像指导的化学和光热(Chem-PTT)治疗。在这里,具有介孔和中空结构(CuSNC)的CuS纳米笼子作为纳米载体,为装载抗癌药阿霉素(DOX)提供了高容量。MnO2纳米壳的外层(MnO2-NS)充当“守门人”,以控制DOX的释放,直到纳米平台到达肿瘤部位,在那里大量的谷胱甘肽和H +将MnO2-NS分解为顺磁性Mn2 +。然后触发磁共振成像和荧光成像以定位肿瘤,由于CuSNC的固有性质,通过光热成像进一步改善了肿瘤。在多模成像的指导下,DOX上的化学疗法和CuSNC上的光热疗法的结合在肿瘤消融方面显示出显着的效率。纳米平台具有生物相容性,可避免在体内转运过程中对正常组织产生有害伤害。因此,这项研究开发出了具有成本效益的TMI纳米平台,该平台具有简便的制备方法,并易于整合多模态成像指导的Chem-PTT治疗能力,从而有可能在精确治疗中应用。DOX上的化学疗法和CuSNC上的光热疗法的结合对肿瘤消融显示出显着的效率。纳米平台具有生物相容性,可避免在体内转运过程中对正常组织产生有害伤害。因此,这项研究开发出了具有成本效益的TMI纳米平台,该平台具有简便的制备方法,并易于整合多模态成像指导的Chem-PTT治疗能力,从而有可能在精确治疗中应用。DOX上的化学疗法和CuSNC上的光热疗法的结合对肿瘤消融显示出显着的效率。纳米平台具有生物相容性,可避免在体内转运过程中对正常组织产生有害伤害。因此,这项研究开发出了具有成本效益的TMI纳米平台,该平台具有简便的制备方法,并易于整合多模态成像指导的Chem-PTT治疗能力,从而有可能在精确治疗中应用。
