In the world of medical technological advancements, there exists already the needle-free drug delivery system. One of the biggest marks against that system, however is the difficulty of getting said medicine through the skin. The skin is our natural protection against the elements and foreign materials. Because of this, we delve into finding unnatural ways to overcome this layer of protection in order to let these vaccines be the most efficient they can be.
The researchers at MIT have come up with a device that uses ultrasonic waves to make the skin more permeable, which will then allow for easier absorption of the medicine being delivered via patch or other needle-less system. It hasn’t been tested on humans yet but the pig skin absorbed insulin 4 times better than via needle-less system alone. Read more here.
