If you’re one of the many adults who hate needles, you may be in luck. Scientists have taken inspiration from squids’ high pressure liquid jets and developed a needle-free device to inject drugs into organs deep within the body.
“Needles require specialized training to administer, present challenges with safe disposal and carry the risk of needle-stick injuries, whether used externally or for deeper, internal applications,” says Giovanni Traverso, a translational engineering researcher at MIT.
To avoid needles’ risks and challenges, Traverso and colleagues designed a microjet device that uses pressure to push drugs such as insulin into a variety of organs. Much like the contractions that squids use to
