Abstract: A method for replicating a structure of a biological tissue provides a plastically deformable film that is subjected to a pressure in order to press it into a mold. The mold comprises formations for pit-like depressions, recesses and notches. The recesses each border on at least one of the pit-like depressions and are opened up. The notches form at least one film hinge in the film. The shaped film is folded into a stack having at least two layers of film, the film hinge forming the folding edge for the folding process. The pit-like depressions are closed along their direction of extension by a neighboring layer of the stack and form each time a capillary. At least two of the opened recesses are arranged one on top of another and form a canal arranged perpendicular to the plane of extension of the film.
