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.
