Sticky Gecko Feet: The Role of Temperature and Humidity
Gecko adhesion is expected to be temperature insensitive over the range of temperatures typically experienced by geckos. Previous work is limited and equivocal on whether this expectation holds. We tested the temperature dependence of adhesion in Tokay and Day geckos and found that clinging ability at 12 degrees C was nearly double the clinging ability at 32 degrees C. However, rather than conf...
متن کاملTowards gecko-feet-inspired bandages.
A novel bandage inspired by gecko feet might one day be used during emergencies and internal surgeries. The bandage uses a combination of nanofabricated structures, biodegradable materials and adhesive surface chemistry that allows adhesion onto even wet, moving tissue.
متن کاملMussels' sticky feet lead to applications.
J. Herbert Waite was a graduate student in biochemistry in the 1970s when he began to wonder how mussels cling to rocks in the turbulent intertidal zone, where they slurp nourishing plankton from the water. So in summers and fall, Waite donned Wellington boots and rubber gloves and headed for the Connecticut shore near Rocky Neck State Park to pluck bivalves from the water. Despite initial skep...
متن کاملIntegrative biology of sticky feet in geckos.
Geckos have gained ecological access to novel microhabitats by exploiting intermolecular van der Waals forces, which allow them to climb smooth vertical surfaces. They use microscopic surface-based phenomena to thrive in a macroscopic mass- and kinetic energy-based world. Here we detail this as a premier example of integrative biology, spanning seven orders of magnitude and a lot of interesting...
متن کاملStaying sticky: contact self-cleaning of gecko-inspired adhesives.
The exceptionally adhesive foot of the gecko remains clean in dirty environments by shedding contaminants with each step. Synthetic gecko-inspired adhesives have achieved similar attachment strengths to the gecko on smooth surfaces, but the process of contact self-cleaning has yet to be effectively demonstrated. Here, we present the first gecko-inspired adhesive that has matched both the attach...
