    摘要: A method for fabricating a nonwoven structure is disclosed. The method comprises: forming a nonwoven layer of polymer fibers on the collector liquid surface, transferring the layer to a solid surface, and repeating the formation and the transfer in a layerwise manner. The method is generally effected by spinning liquefied polymer, in particular by employing electrostatic or hydrostatic forces. The nonwoven structure formed comprises of plurality of nonwoven layers: the average thickness of the nonwoven structure is at least 0.5 mm and the structure has an overall porosity of at least 90%. The nonwoven structure an be used in forming a scaffold for tissue engineering, in particular a cell-scaffold composition, suitable for implanting in a patient, wherein at least one cell population is seeded on at least one of the plurality of layers.
