Researchers have developed a system to deliver medical treatments at the right time and with minimal invasiveness using magnetic particles in lipids. The drug is inserted into the fatty molecule bubbles, which contain the magnetic particles, and released by heating the particles with a magnetic field, enabling them to break out of the bubble and spread. In this study, researchers from the University of California, San Diego, used nanoparticles that are able to release drugs when they encounter certain types of lipid molecules. The researchers said the initial work focused on neurological problems, but it could be used for cancer drugs or painkillers.

The magnetic switch could also be theoretically used to guide drugs to particular places inside a patient.
