MIT scientists successfully replace surgical sutures with double-sided tape

Surgical stitches are commonly used to heal large wounds. Their disadvantage is the possibility of internal tissue damage, which can lead to infection. A special adhesive tape developed by scientists at the Massachusetts Institute of Technology will help to avoid this.

The know-how idea is that the pieces of tape are applied to the edges of the wound to be joined. Once fixed with tape, they heal and heal faster.

The tape contains strips of gelatin and chitosan, absolutely harmless to the body, which disintegrate within a few days after being applied to the wound.

On both sides of these strips are polyacrylic acid, commonly used in diapers to absorb liquid. The acid can also form weak hydrogen bonds with already dry surfaces, sticking them together.

To date, the tape has been successfully tested on pig tissue - on the skin, small intestine, stomach, liver, lungs and trachea. Scientists hope that the material they have developed will be able not only to promote wound healing, but also allow biomedical implants to be fixed on the body.
