Researchers working at jointly at Harvard and MIT are trying to develop a nanoparticle drug delivery system that will release medication on demand. The nanoparticle will have a piece of DNA and a magnet attached to it. The nanoparticle would travel through the bloodstream to the targeted tissue. Once the particle reach the targeted tissue, and electromagnetic field can be applied and the medication in released.
