Slug and surgical glue
Summary
Host Patrick Aye explores how slug slime inspires advanced surgical adhesives in this episode of 30 Animals That Made Us Smarter. Scientists at Harvard’s Wyss Institute mimicked the dusky Orion slug’s viscoelastic mucus to create a strong, flexible, and wet-resistant glue. This biomimetic material can seal wounds on delicate organs like hearts and livers without damaging tissue, offering a promising alternative to traditional stitches and staples.
