Sticky or slippery? Snails can change their slime to meet the moment
Researchers have discovered that brown-lipped snails can produce five distinct types of mucus by adjusting protein and ion proportions. This biological mechanism offers potential inspiration for engineers developing new materials like surgical glues or drug delivery systems.
Why it matters
Understanding natural material synthesis provides a blueprint for biomimetic engineering, potentially leading to advancements in medical adhesives and drug delivery.
Slime is splattered across the animal kingdom. Tubeworms produce mucus that glows. Hagfish can make buckets of slime in an instant. And then there are snails.
"Snail slime specifically is fascinating — a natural work of art," says Mariella Gabler , a Ph.D. student in physical chemistry at the Max Planck Institute of Colloids and Interfaces in Germany. "The complexity and functionality are mesmerizing."

To that end, Gabler and her colleagues wanted to know more about the composition of the slime of a particular kind of terrestrial species that's native to central Europe, called Cepaea nemoralis , or the brown-lipped snail.
