Abstract
We have developed a novel construct of magnetic iron oxides nanoparticles (MNPs) and two chemotherapy drugs (doxorubicin and gemcitabine), which were loaded in a liposomal system to boost the therapeutic effect and reduced the systemic toxicity of the cancer treatment. The synergism and stability of the liposome have already been demonstrated in our in vitro study. However, MNPs are readily excreted by the kidney or taken up by the Kupffer cells in the liver. Thus the in vivo biodistribution of the thermosensitive liposome is vital for evaluating the efficiency and translating our result from bench to bedside. Biodistribution study by using radiotracer is one of the most efficient methods of tracking the drugs, MNPs, and liposomes in an animal model.
