Professor Mu Chiao’s lab at UBC has developed a magnetic implant that offers controlled delivery of a drug to an internal target site. The device, a silicone sponge with magnetic iron oxide particles and a polymer layer, measures just six millimetres in diameter. A drug can be injected into the device, which is then surgically implanted into the treatment area. Passing a magnet over the patient’s skin activates the device by deforming the sponge and triggering the release of the drug into surrounding tissue through a tiny opening. This offers a pathway to controlled in vivo drug delivery using biocompatible materials.
