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.
We are angry, frustrated, and in pain because of the violence and murder of Black people by the police because of racism. We are in the fight AGAINST RACISM. George Floyd was murdered, his life stolen. The Adafruit teams have specific actions we’ve done, are doing, and will do together as a company and culture. We are asking the Adafruit community to get involved and share what you are doing. The Adafruit teams will not settle for a hash tag, a Tweet, or an icon change. We will work on real change, and that requires real action and real work together. That is what we will do each day, each month, each year – we will hold ourselves accountable and publish our collective efforts, partnerships, activism, donations, openly and publicly. Our blog and social media platforms will be utilized in actionable ways. Join us and the anti-racist efforts working to end police brutality, reform the criminal justice system, and dismantle the many other forms of systemic racism at work in this country, read more @ adafruit.com/blacklivesmatter
