An innovative microneedle capsule could one day allow diabetics to take their medication orally.
The capsule developed by a team from MIT and Novo Nordisk is designed to travel though the stomach to the small intestine. Once in the intestine, the higher pH level breaks down the capsule to expose its microneedles, which lodge in the intestinal wall. The device then releases its payload of medication into the bloodstream before safely dissolving away.
The capsule has been successfully tested on pigs, and the team believes it could also be used to deliver other protein-based drugs that usually require injections, such as hormones or enzymes.
