Abstract

Purpose: Achieving new contrast enhancer agents that can produce high-resolution images in magnetic resonance imaging (MRI) with a minimum dose and side effects has always been important. Methods: Herein, the pegylated curcumin-coated manganese–zinc ferrite nanoparticles (MZF@CA-PEG-CUR NPs) have been reported as an MR imaging nanoprobe in hepatocellular carcinoma detection in the murine model for the first time. In vitro studies were done on HEPA 1–6 cancer cells and L929 as normal cells, and in vivo studies were done on hepatocellular carcinoma (HCC) using xenograft models of HCC. Results: The prepared NP had a diameter of 105 nm with narrow size distribution and was superparamagnetic with a saturated magnetization (Ms) of 39 emu/g. The NP was biocompatible without any significant hemolysis and cytotoxicity. Prussian blue staining showed more cellular uptake of HEPA 1–6 compared to L929 control cells after incubation (P < 0.05). The concentration of Fe in mice blood confirmed the plasma half-life of about 3 h; it seems the PEGylation increased the circulation time. ICP-OES of Fe showed the highest tumor localization for MZF@CA-CUR-PEG NPs, due to passive accumulation, compared to the other mice studied organs. The r2 relaxivity of NPs was 134.89 mM− 1 s− 1, and in vitro MRI demonstrated better effects in HEPA 1–6 cells than in L929 (P < 0.05). Also, in vivo MR images showed signal enhancement efficacy in tumor-bearing mice. Conclusion: This study demonstrated that the MZF@CA-CUR-PEG nanoprobe could be a promising candidate as an MR imaging agent in hepatocellular carcinoma early detection. © 2022, The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature.
