摘要:

在诊疗一体化大背景下, 通过设计新颖的纳米材料以实现多模式成像备受关注. 其中, 磁共振和荧光成像是临床常用的成像手段, 将这两种成像方法结合起来实现双模式成像, 可为疾病诊断提供更大便利. 本文采用微乳液模板法将具有T2磁共振成像功能的Fe3O4纳米粒子与具有荧光成像功能的CuInS2纳米粒子共组装, 制备了Fe3O4/CuInS2二元超粒子. 使用生物相容性良好的聚乙二醇-聚乳酸-羟基乙酸嵌段共聚物对二元超粒子进行修饰, 提高了其生物安全性. 该二元超粒子除具有双模式成像功能外, 引入的Fe3O4纳米粒子还赋予其光热治疗潜力, 并可以作为载体负载紫杉醇等药物, 为实现成像引导下的肿瘤联合治疗提供了机会.

Abstract:

Multimodal imaging techniques have attracted great attention under the background of tumor theranostics, which are promoted by the development of nanomaterials. Magnetic resonance imaging(MRI) and fluorescence imaging are clinically used imaging techniques, the combination of which will establish novel dual mode imaging methods and facilitate disease diagnosis. In this work, Fe3O4/CuInS2 binary superparticles(SPs) are fabricated through the co-assembly of Fe3O4 nanoparticles(NPs) with T2 MRI function and CuInS2 NPs with fluorescence imaging function using oil-in-water droplets as the templates. The biosafety of the SPs is improved through the modification with biocompatible methoxy poly(ethylene glycol)-poly(lactide-co-glycolide)(mPEG-PLGA). Besides the dual mode imaging, the constituent Fe3O4 NPs endows the SPs with a photothermal effect. The SPs can be also employed as nanocarriers for loading anti-tumor drugs, such as paclitaxel(PTX). The current work provides a new chance for the development of imaging-guided tumor therapeutics.
