Targeted Therapy of Non-Small Cell Lung Cancer and Liver Cancer: Functional Nanocarriers for the Delivery of Cisplatin and Tissue Factor Pathway Inhibitor-2.

Introduction: The aim of the study was to construct folic acid-modified PEGylated paramagnetic nanoparticles (MNPs) co-carrying tissue factor pathway inhibitor-2 (TFPI-2) and cisplatin (CDDP), and to study the molecular-targeting and inhibitory effects of the nanocomposite on non-small cell lung cancer (NSCLC) and liver cancer.

Methods: Nanocomposites were prepared using amino-modified iron oxide nanoparticles as carriers, co-loading CDDP and PEGylated FA/TFPI-2. Transmission electron microscopy, UV absorption spectrum, and dynamic light scattering were employed to characterize the morphology, structure, particle size, and zeta potential of the nanocomposite.
