Tiny magnetic implant delivers drug locally

Researchers from the University of British Columbia have developed a magnetic drug implant that measures just 6 millimeters in diameter and can deliver a drug locally to a targeted tissue. The team’s work was published in the journal Advanced Functional Materials.

The device is a silicone sponge with magnetic carbonyl iron particles, wrapped in a round polymer layer. After the device is loaded with drug, it is surgically implanted into the area being treated. To activate the device, researchers passed a magnet over the patient’s skin and deformed the sponge, initiating the drug’s release into surrounding tissue through a small opening.
