Scientists at Northwestern University have developed the hybrid oxygenation bioelectronics system for implanted therapy (HOBIT), a wireless device that can produce and deliver multiple drugs at once. In tests with rats, the device provided reliable amounts of three drugs at the same time, including a GLP-1 medication. The researchers also demonstrated that it could keep engineered cells alive for at least a month inside the body, thanks to a self-sustaining source of oxygen. The technology could potentially serve as a platform for cell therapy with minimally invasive implants. The team plans to test their device in larger animals and use it to treat other health conditions.
