Schemes of a) the structure of Lam-111 and polymerization. The representation of the long arm consisting of a triple-helix is simplified for clarity, b) the proposed organization of Lam-111 at the air–water interface during compression together with the resulting thickness profiles of the deposited film, and c) fabrication and characterization of gradient Lam-111 LB-film via microscopy and by culturing hADSC on the film. w, the width of the barrier; A_S, start area of the surface; A_E, end area of the surface; ν_c, compression speed; ν_D, lifting speed of the substrate; L_G, gradient length.
