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.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
