| Zusammenfassung: | © 2017 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim. A multifunctional core-satellite nanoconstruct is designed by assembling copper sulfide (CuS) nanoparticles on the surface of [89 Zr]-labeled hollow mesoporous silica nanoshells filled with porphyrin molecules, for effective cancer imaging and therapy. The hybrid nanotheranostic demonstrates three significant features: (1) simple and robust construction from biocompatible building blocks, demonstrating prolonged blood retention, enhanced tumor accumulation, and minimal long-term systemic toxicity, (2) rationally selected functional moieties that interact together to enable simultaneous tetramodal (positron emission tomography/fluorescence/Cerenkov luminescence/Cerenkov radiation energy transfer) imaging for rapid and accurate delineation of tumors and multimodal image-guided therapy in vivo, and (3) synergistic interaction between CuS-mediated photothermal therapy and porphyrin-mediated photodynamic therapy which results in complete tumor elimination within a day of treatment with no visible recurrence or side effects. Overall, this proof-of-concept study illustrates an efficient, generalized approach to design high-performance core-satellite nanohybrids that can be easily tailored to combine a wide variety of imaging and therapeutic modalities for improved and personalized cancer theranostics in the future |
