This study aimed to design and evaluate enhanced permeation and retention (EPR)-mediated anticancer effect of polymer-modified and drug-loaded magnetite nanocomposites. The preformulated bare (10 nm), chitosan-superparamagnetic iron oxide (SPIO; 69 nm), heparin-SPIO (42 nm), and (3-aminopropyl)triethoxysilane-polyethylene glycol-SPIO (17 nm) nanocomposites were utilized to evaluate the EPR-mediated localized cancer targeting and retention of doxorubicin (DOX) and paclitaxel (PTX) in human ovarian cancer cell lines, A2780 and OVCAR-3 in vitro and in the tumor-baring Balb/c mice in vivo. Fluorescence microscopy showed that DOX- and PTX-loaded SPIO nanoparticles caused long-term accumulation and cytoplasmic retention in A2780 and OVCAR-3 cells, as compared to free drugs in vitro. In vivo antiproliferative effect of present formulations on immunodeficient female Balb/c mice showed a tremendous amount of ovarian tumor shrinkage within 6 weeks. The present nanocomposite systems of targeted drug delivery proved to be efficient drug carrier with sustained drug release and long-term retention with enhanced cytotoxic properties in vitro and in vivo.
