Purdue researchers have created an implantable drug-delivery system using nanowires that can be controlled wirelessly.
The nanowires respond to an electromagnetic field generated by a device used to control the release of a preloaded drug. Tubes and wires required by other implantable devices are eliminated, minimizing the risk of infection and complications.
According to lead author Richard Borgens: “This tool allows us to apply drugs as needed directly to the site of injury, which could have broad medical applications, The technology is in the early stages of testing, but it is our hope that this could one day be used to deliver drugs directly to spinal cord injuries, ulcerations, deep bone injuries or tumors, and avoid the terrible side effects of systemic treatment with steroids or chemotherapy.”
