Nanocapsules containing intentionally trapped magnetic nanoparticles and defined anticancer drugs have been prepared to provide a powerful magnetic vector under moderate gradient magnetic fields. These nanocapsules can penetrate into the interior of tumors and allow a controlled on-off switchable release of the drug cargo via remote RF field. This smart drug delivery system is compact as all the components can be self-contained in 80-150 nm capsules. In vitro as well as in vivo results indicate that these nanocapsules can be enriched near the mouse breast tumor and are effective in reducing tumor cell growth.
