Inspired by the sticky substance of the spiders use to catch their prey, Massachusetts Institute of Technology (mit) engineers have developed a special double-sided adhesive tape that will soon be able to seal the tissues together, according to the researchers.
The new discovery has only been tested in rat and pig tissues — including the small intestine, the stomach, the liver, and the skin-but scientists are hoping that it will eventually replace the joints, that is to say, they don’t always work and can lead to infection.
They found that the new tape to bind the tissue and within five seconds, according to MIT News.

Inspired by the sticky substance of the spiders are shooting at their prey to catch it, MIT engineers have developed a special double-sided adhesive tape that will soon be able to seal the tissues together.
“There are more than 230 million major operations worldwide each year, and many of them will need stitches for the wound to close it, which can actually cause stress on the tissue and can cause infection, pain and scarring. We propose a fundamentally different approach to the waterproofing of the fabric,” Xuanhe Zhao, an associate professor of mechanical engineering and senior author of the study, told MIT News.
Scientists have witnessed the formation of a good seal between the tissue, it is very difficult because of the water on the surface of the fabric smooth. They also found that the glue can take a few minutes to get to work, and sometimes it trickles to other parts of the body.
Spiders secrete a viscous material with an amount of polysaccharides that absorb the water from the surface of the prey almost instantly, according to the BBC.
What’s left is a small dry patch on which the adhesive is able to keep up.

The researchers mimicked this natural “glue,” due to the use of polyacrylic acid, that is, the material that is used in diapers to absorb water, according to MIT News.
They put it on the tape, to absorb the water from the water body’s tissues, which, they say, has resulted in the glue will stick quickly.
With the addition of gelatin or chitosan, the experts determined, they will be able to use the tape, press and hold for a few days, or a month, depending on their needs.
The researchers tested this method on pigs, the lungs and tracheas, two kinds of bodies, which, they say, are a challenge to repair, if with the help of sutures.
“It is very challenging to suture, soft or delicate tissues, such as the lungs and the trachea, but the double-stick tape, and within five seconds, it is easy to seal,” Yuk said, according to MIT News.
Scientists are now saying that they are planning to carry out more tests on animals, even though they have a certain number of years of trial and testing in a human being.

She added that she is working on the development of the applications of this new type of bonding in the future.
