Multifunctional nanoparticles (NPs) were prepared based on temperature-induced phase transition in a molten mixture of Lipiodol®, Tween 80, paclitaxel (PTX), and Pluronic F-68, wherein the Lipiodol®/Tween 80 mixture is used as a solubilizer for PTX, and Pluronic F-68 is used for the stabilization of the molten mixture. The morphology and size distribution of optimized multifunctional NPs were observed using transmittance electron microscopy (TEM) and a particle size analyzer. In the optical imaging of tumor-bearing mice using a near-infrared fluorescence (NIRF) imaging system, the multifunctional NPs were evaluated in terms of a time-dependent excretion profile, in vivo biodistribution and tumor-targeting capability compared to free fluorescence dye. In addition, the prolonged circulation of multifunctional NPs was confirmed by enhancement of the blood-pool in live animals using a micro-CT imaging system, because iodine-containing Lipiodol® has an X-ray enhancement property. Finally, the anti-tumor efficacy of multifunctional NPs was monitored by injecting the multifunctional NPs into the tail veins of tumor-bearing mice. The multifunctional NPs showed excellent tumor targetability and anti-tumor efficacy in tumor-bearing mice, caused by the enhanced permeation and retention (EPR) effect.
