A new glue inspired by slug slime can mend a broken heart.
강원 랜드 바카라 이기는 법 arteries, liver tissue and hearts — including hearts that were inflated with water or air and covered in blood. The material proved extremely stretchable, expanding 14 times its original length without ever breaking loose from the liver tissue. When used to patch a hole in a pig heart, the adhesive maintained its seal even when it was stretched to twice its original length tens of thousands of times, at pressures exceeding normal human blood pressure.
The researchers even applied the adhesive to the beating heart of a real pig and found that the adhesion to the dancing, bloody surface was about eight times as strong as the adhesion of any commercially available surgical glue.
The glue was also tested in a living rat: The researchers simulated an emergency surgery by slicing the rats’ liver tissue and then patching the wound with either the glue or a standard blood-staunching product called Surgiflo. They found that the new adhesive was as good at stopping the blood flow as the standard glue; the rats treated with the new glue experienced no additional hemorrhaging up to two weeks after the surgery. The Surgiflo-treated rats, however, sometimes suffered from tissue death and scar tissue, the researchers reported. The rats treated with the slime-inspired glue did not experience these side effects.
Whether the new glue makes it to the operating room depends on much more extensive clinical testing, Li said, but the adhesive could make its debut as a new method of dressing external wounds on a shorter timeline than that.
“We have a company working on trying to push our material to clinical applications, and we have a patent pending,” Li said.
