Gallery: MIT Scientists Develop Stronger Adhesives and Less Painful Nee...


Porcupine quills might seem more hurtful than helpful – but researchers at MIT and Brigham and Women’s Hospital are examining the structure of the spines for use in the medical field. For the first time, scientists have characterized the forces needed for the quills to enter and exit the skin and have created devices mimicking their characteristics. The designs are the first steps towards less painful needles and stronger adhesives. This will particularly benefit patients who have undergone such delicate internal surgeries as most of their wounds are currently held together with sutures or staples that can leak, or adhesives that can cause adverse reactions.
