Many cancer patients do not respond to chemotherapies because the drugs never reach the cancer cells. Even in nanomedicine, which is one of the best new methods for delivering drugs to a tumor, only about one percent of a dose of nanoparticles will successfully arrive at the intended tumor site, while the rest are filtered out by the immune cells of the liver and spleen.

Using chloroquine, the researchers not only increased the circulation of nanoparticles in the body, but also reduced the body's filtration of nanoparticles, as well as improved drug delivery to breast tumors. The study was recently published inĀ Scientific Reports, a research journal from the Nature Publishing Group.
