Remotely Controlled Drugs

December 6, 2007 | Source: Technology Review

MIT engineers are developing remote-controlled, multipurpose nanoparticles. These compounds act as both precise drug-delivery vehicles and contrast agents for magnetic resonance imaging (MRI).

Nanoparticles implanted in model tumors in mice release a drug (dyed green) into surrounding tissues when the mouse is exposed to radio-frequency waves (Sangeeta Bhatia, MIT)
