The Challenge

After surgeries and other medical procedures, the broken skin is patched back together with stitches or staples to assist in healing. Both of these methods lead to scarring and a greater chance of infection due to the damage caused to the skin.

Innovation Details

The adhesive material is a unique hydrogel that contains synthetic recombinant versions of the proteins found in slug adhesives. These proteins bind with other proteins to form a three-dimensional network. This network is stiff but contains sacrificial bonds to absorb energy, protecting the underlying carbohydrates within the hydrogel. Additionally, there are chemical bonds within the network that can be changed to modify the glue’s strength. Overall, the adhesive is strong yet flexible, and is safe for use in medical applications.

Biomimicry Story

Slugs have a slimy coat that leaves a trail of slime as they move. When a slug needs to protect itself against a predator, it adds certain proteins to its natural slime to convert it into a harmful adhesive. The adhesive traps predators and prevents them from eating the slug.
