Everyone who had the misfortune to experience the effect of porcupine quills, know that they are extremely difficult to remove their skin. Scientists at the Massachusetts want to use this property to create a new special glue and other materials for medical purposes.
For patients who have undergone surgery on the stomach or intestines, this adhesive is a godsend. Now these surgical incisions doctors sealed seams or staples. This is a very unreliable way, as the wound may leak and cause complications. Besides seams and stitches doctors sometimes have to use a special medical grade adhesive for tissue tightening. However, these adhesives are toxic and harmful to the body. The solution to this problem, American scientists assembled from nature, but rather from a porcupine.
Each needle porcupine cover microscopic grooves. The peculiarity of these needles is that they pierce tissue with almost no effort and is extremely difficult to remove them. The fact that the needle tip has tiny barbs which facilitate penetration into the skin and prevent the extraction of the needle. Striae with teeth act as anchors, so removing senticosus pen must make four times harder than the smooth recovery needle.
Researchers have tried a bit to correct this natural technology and make it so that the needles were removed from the fabric without any problems. Scientists first identified what force is required to enter and exit the porcupine needles into the skin, and then develop artificial devices that have the same properties, but less painful. This new "spetskley", which is unparalleled, allows you to securely connect internal tissues. In the future, the scientists plan to create a new class of wound dressings based biomaterials, modeled on the basis of porcupine quills.
