Tape, glue, staples. No not a variation on rock, paper, scissors, this is the way that doctors hold things in place in your body. Inspired by those fun loving parasites that attach in your digestive organs and hold on while they eat, scientists at Brigham Women’s Hospital have engineered tiny needles based upon the way that parasites attach to the intestines. The needles swell when they are exposed to water and then hold on. This approach is 3-5 times better than surgical tape and could be used to attach patches that deliver different medicines. Ouch, it might hurt to remove it though.
