A small capsule could change how we take some medications
A team of scientists have developed a special capsule for diabetics, which could replace insulin injections. The key to the capsule is its design — inspired by the shell of an African leopard tortoise. The capsule has high, rounded sides that guarantee it can flip over if it lands upside down. This is important because it ensures the medicine is delivered correctly. The flat bottom keeps it in position once it lands.
The pill is small, about the size of a blueberry, making it easy to swallow. The capsule contains a small biodegradable needle made of compressed insulin. It releases the insulin once in place. The mechanism was a eureka moment for the team. The scientists realised the humidity of the stomach would dissolve a disk of sugar. They used the disk to hold the needle in place until it reached the stomach lining.
