DOI: 10.1002/smll.202201674
Abstract: A multiscale modeling approach is used to develop a particle-based mesoscale gecko spatula model that is able to link atomistic simulations and mesoscale (0.44 µm) simulations. It is used to study the detachment of spatulae… read more here.

DOI: 10.1002/smll.202206085
Abstract: A higher relative humidity leads to an increased sticking power of gecko feet to surfaces. The molecular mechanism responsible for this increase, however, is not clear. Capillary forces, water mediating keratin-surface contacts and water-induced softening… read more here.

DOI: 10.1007/s00709-018-1270-9
Abstract: The digital adhesive pads that allow gecko lizards to climb vertical surfaces result from the modification of the oberhautchen layer of the epidermis in normal scales. This produces sticky filaments of 10–100 μm in length, called… read more here.

DOI: 10.1007/s40544-020-0387-3
Abstract: Adhesion achieved through feet setae is fundamental for gecko agilely maneuvering. Although diverse hypotheses have been proposed, none of them thoroughly explains the setae function, implying a kind of hybrid-mechanism-based adhesion in geckos. In addition… read more here.

DOI: 10.1038/s41598-020-76484-6
Abstract: Gecko adhesive performance increases as relative humidity increases. Two primary mechanisms can explain this result: capillary adhesion and increased contact area via material softening. Both hypotheses consider variable relative humidity, but neither fully explains the… read more here.
