Abstract
front page image (EN)A method is described for producing a microfluidic device (19), which comprises the phases of producing a three-dimensional template (15) of geometry equal to the channelings that is desired to obtain in the device; inserting the template in the desired position into a mould (16), keeping it suspended by at least one of its end; coating said template by immersion in (or deposition of) a material in the liquid phase (or dissolved or dispersed in a solvent) capable of solidifying by means of a chemical reaction or physical transformation, forming a material constituting the body of the final device; and selectively removing the three-dimensional template. In a variant of the method, useful for the production of scaffolds to be inserted into the human body, a porogenic material is added to the liquid precursor or to the precursor solution, such that the material of the solid matrix is characterised by a continuous structure of pores into which it is possible to insert live cells.Pubblicazioni consigliate
