Close to the tip, the diameter of the adhesive tarsal setae depends significantly on the hydration condition of the material. While dried setae feature diameters of 2.0±0.1 μm, fresh ones ...

本研究针对玉米根萤叶甲(Diabrotica virgifera virgifera)在复杂基质上的附着机制展开，通过比较雌雄个体跗节(tarsus)形态差异与力学性能，首次发现雄性特有的蘑菇形黏着刚毛(adhesive setae)及其在交配中的特殊功能。研究结合显微成像、白光干涉仪和力学测试，揭示雄性附着性能(N m?1 )显著优于雌性(0.9 vs 0.2 ...

Dragging the setae across two surfaces (one that repelled water and another that attracted water) at different velocities and in environments ranging from 10% to 80% humidity, ...

Spiderman's setae, chemical coating, and van der Waals forces work together to enable him to stick to walls and ceilings, representing the science behind his wall-crawling abilities (Image via Sony) ...

Adhesion results and the setae are ready to bear the full load of the animal¿s body weight, whether it's scampering up a wall or across a ceiling. On supporting science journalism.

The sticky setae evolved from tiny hair-like growths called spinules, which cover the body of all geckos and are thought to help them shed their skin.

Setae provide sticking power because they are flexible and assume the microscopic contours of whatever surface the gecko is climbing. Even smaller structures at the ends of the setae, ...

Setae will bond with the dust, not the surface, and if it slips, so will the gecko, Russell says. The same goes with "oil or very soft materials, [which] don't allow strong connection with setae ...
