Lamelo (zoologio)
Lamelo aŭ foje lameno, estas fajna plateca strukturo, ofte unu inter multaj lameloj tre proksima unu de alia, kun malferma spaco interne. Krom ĉe spira organaro, ili aperas en aliaj biologiaj funkcioj kiaj filtromanĝo, la algluigaj surfacoj de gekoj,[1] kaj kloroplastaj membranoj kie alta akvomalimuneco gravas.

(2007) “[1]”, Journal of Adhesion Science and Technology 21 (12-13), p. 1317–1341. “Gecko "feet and toes are a hierarchical system of complex structures consisting of lamellae, setae,and spatulae. The distinguishing characteristics of the gecko adhesion system have been described [as] (1) anisotropic attachment, (2) high pulloff force to preload ratio, (3) low detachment force, (4) material independence, (5) self-cleaning, (6) anti-self sticking and (7) non-sticky default state. ... The gecko’s adhesive structures are made from ß-keratin (modulus of elasticity [approx.] 2 GPa). Such a stiff material is not inherently sticky; however, because of the gecko adhesive’s hierarchical nature and extremely small distal features (spatulae are [approx.] 200 nm in size), the gecko’s foot is able to intimately conform to the surface and generate significant attraction using van der Waals forces.”.
