Abstract
Herein, we report the fabrication of a novel class of magnetofluorescent theranostic nanoparticles (MFTNPs) based on "surface-complexation" of zinc ferrite (ZnFe2O4) NPs with 8-hydroxyquinoline. The potential of these MFTNPs in fluorescence-based bioimaging of different cancer cells was successfully demonstrated. The superparamagnetic behavior of the MFTNPs was exploited effectively in magnetic targeting in vitro. Finally, a well-known hydrophobic antimalarial and prospective anticancer drug artemisinin was efficiently loaded into MFTNPs. Artemisinin loaded MFTNPs were observed to induce superior antiproliferative response, as compared to free drug, in cancer cells in a synergistic mechanism with combination index of 0.1 or less.
