Abstract

A novel theranostic nanoplatform was prepared based on Fe3O4 nanoparticles (NPs) coated with gadolinium ions decorated-polycyclodextrin (PCD) layer (Fe3O4@PCD-Gd) and employed for Curcumin (CUR) loading. The dissolution profile of CUR indicated a pH sensitive release manner. Fe3O4@PCD-Gd NPs exhibited no significant toxicity against both normal and cancerous cell lines (MCF 10A and 4T1, respectively); while the CUR-free NPs showed more toxicity against 4T1 than MCF 10A cells. In vivo anticancer study revealed appropriate capability of the system in tumor shrinking with no tissue toxicity and adverse effect on body weight. In vivo MR imaging of BALB/c mouse showed both T1 and T2 contrast enhancement on the tumor cells. Fe3O4@PCD-Gd/CUR NPs showed significant features as a promising multifunctional system having appropriate T1-T2 dual contrast enhancement and therapeutic efficacy in cancer theranostics. © 2020 Elsevier Ltd
