Abstract

Owing to the importance of multifunctional theranostics as promising systems to overcome key problems of conventional cancer therapy, in this study a multifunctional metal–organic framework-based (MOF) theranostic system was prepared and applied as intelligent theranostic systems in cancer. Iron-based MOF, MIL-88B, in a multi-faceted shape was initially prepared. Curcumin (Cur) was then loaded into the pores of MIL and folic acid–chitosan conjugate (FC) was finally coated on the surface of the carrier to accomplish cancer-specific targeting properties. MTT assay revealed perfect cytocompatibility of the system and selective toxicity against cancerous cells. In vivo MRI images showed high tumour uptake for MIL-Cur@FC and high T1–T2 contrast effect. The growth inhibiting efficiencies of MIL-Cur@FC on M109 tumour bearing Balb/C mice without reducing their body weight showed maximum tumour eradication with no significant toxicities. Due to the outstanding features of the system achieved from in vitro and in vivo studies, we believe that this study will provide a novel approach for developing targeted theranostic agents in cancer diagnosis and treatment. © 2020, © 2020 Informa UK Limited, trading as Taylor & Francis Group.
