MIT has double-sided adhesive that can be used to seal tears in lungs and intestines. It can also detach from the tissue without causing any damage. Magic Tape for the inside. Here’s more from SlashGear:
The make the adhesive detachable. The team tweaked the adhesive itself using a new disulfide linker molecule that can be placed between covalent bonds with the tissue surface protein. That particular molecule has strong bonds that can be easily separated if exposed to a particular reducing agent. The team then researched suitable reducing agents that were biocompatible and able to sever the bonds. The search landed on glutathione or baking soda. Once applied, the adhesive could be peeled from the tissue in about five minutes with no damage.
