Materials science: How to suck like an octopus
Rubber sheets that reversibly bind and release substrates have been made by copying a subtlety in the shape of octopus suckers. The findings reveal how macro-scale biological structures can influence function.
Ask beachgoers how mussels, barnacles and oysters attach themselves to rocks, and they will often guess that suction cups are involved. Actually, these shellfish use adhesives. But go a little deeper into the water, and you will find organisms that do use suckers: octopuses. These soft-bodied animals use suction cups for surface attachment, locomotion and grabbing their next meal. On page 396, Baik et al.1 report adhesive patches that are synthetic mimics of octopus suckers. The authors go beyond simply copying suction cups by discovering a specific architectural feature that enhances adhesion.
