 There's actually not really good surgical adhesive out there, so you can use things like sutures and staples, but they have their drawbacks. Sutures and staples are always going to punch holes into the skin or into the tissue that you're working with, and then in some cases you also need to go back and remove them. So we're trying to make a glue that surgeons or doctors could use that would be a good material, have strong adhesion, and would also be good material for soft tissue. So things like your skin or internally some of the soft organs inside of your body. We've engineered this protein to have some of the properties that we're interested in, so one of those properties is to make sure that it's adhesive. To do that we've incorporated a molecule that's sticky, it's called DOPA, and this is inspired by muscles from the ocean. So they secrete a protein that allows them to stick to rocks. Another property we're interested in is having it be elastic, and so we were inspired by a protein actually found in your skin. The last one has a unique property that allows it to phase separate. So when you warm up the protein solution, what happens is you have two different phases. One phase is protein-rich, it's dense and it's at the bottom. Another phase is somewhat like water and it sits on top. The dense phase allows it so that when you dispense the material, it will actually stay in place where you've put it, and so it doesn't get dispersed into blood or other fluids in your body.
